Rainy today

Hello everyone!

Today will feature rain this morning tapering to drizzle and fog this afternoon. Highs will be very warm in the 50’s brought to you by winds out of the south at 15-20 mph. I do not expect any clearing today except for far SWCT.

Sunny and warm today

Hello everyone!

Today will feature sunny skies and mild temps as high pressure is in firm control of our weather. Highs will be in the 50’s inland and near 50 at the coast as an onshore breeze will keep temps down. A few high clouds may filter in this afternoon ahead of our next storm.

Monday morning forecast map 4-7

Our next storm arrives tomorrow with rain. 1-2″ of rain is expected falling before noon.  Afternoon features partial clearing with the chance for southern areas to see their first 60’s of the season. More sun midweek with rain returning Friday. Sun and 60’s COULD be in the cards for next weekend.

Half and Half today

Hello everyone!

Today will be split in half with the not so nice half occurring now as a front passes through. However, most of the precip has moved out of the area so as a result, the clearing can commence earlier than expected. This afternoon will feature a mix of sun and clouds along the coast with breezy west winds. Highs will be  in the upper 40’s to low 50’s.

Tomorrow will be even better with sun and low 50’s. Monday continue the trend, sunny and 50’s. Tuesday features really warm temps in the mid 50’s with rain in the morning and then possibly sun in the afternoon. No big storms are in sight.

Clouds increase today

Hello everyone!

Today will feature sun turning to clouds as a storm approaches. Highs will top out near 40 in most locations. Despite the clouds, we should stay dry this afternoon. West of the CT river valley is where the best chance for some precip is.

Friday morning forecast map 4-4

Beyond today, Sunday and Monday look lovely with sun and 50’s. Tuesday will be very warm with a shot at 60. Tuesday will also feature rain however. No big storms are in sight.

Return to sun today

Hello everyone!

Today will feature a return of the Sunshine that brought us a wonderful day Tuesday. Highs will be in the 40’s to near 50, coolest at the coast. Coastal areas will see temps near 40. As much as we hate the sea breeze now, we’ll be happy in August when it’s 75 here and 95 inland.

Clouds will dominate the morning hours though they will burn off rather fast. Anything after 11 or 12 looks fantastic.

Thursday morning forecast map 4-3

Tomorrow, clouds increase in the afternoon ahead of our next storm for Saturday. Sunday and Monday look nice with temps near 50. Tuesday morning features rain with clearing in the afternoon. Temps COULD hit 60.

More clouds today

Hello everyone!

Today will feature a few more clouds as a weak cold front passes through. Temps though will still be pretty warm with highs in the 40’s possibly hitting 50 in some spots.

Wednesday morning forecast map 4-2

Tomorrow will feature a return to full sun with more 40’s. Saturday looks wet as a strong front and associated coastal low pass over the region. Sunday and Monday look good with sun and warm temps (50’s Monday!!) More rain is in the forecast for Tuesday.

Storm moves away

Hello everyone!

Today will feature Partly Cloudy skies for most of the region with less clouds farther West and more East. Far eastern parts of the state will continue to pick up snow but little accumulation is expected. Temps will be very pleasant with highs in the mid 40’s. The only fly in the ointment st to speak will be stiff northerly winds gusting over 20 mph at times.

Thuesday morning forecast map 4-1

Tomorrow features more clouds as a weak front passes through.

Thursday features sun and 40’s.

Friday will bring more clouds and warm temps.

On Saturday we will get another round of heavy rain  with another front and coastal low.

Storm continues today

Hello everyone!

Today will feature more wet weather with the chance for frozen precip away from the immediate coast. Rain/frozen precip will be mainly light to moderate but could become heavy later this morning. An additional inch of rain is expected.

Monday morning forecast map 3-31

An overview of today’s weather. Anywhere in purple is where you have to watch for icy conditions thorough not all areas there will have icy conditions.

Winds will also be a factor today gusting out of the North at over 20 mph at times. This will draw in colder air leading to frozen precip.

Tomorrow features clearing skies and winds out of the WNW at 10-15 mph. Temps will be a bit warmer though still not all that warm.

Another system moves though Wednesday with little fanfare, just some clouds and the slight chance for a shower. Temps will rise into the 40’s.

Sun and 40’s rule Thursday. Things cloud up Friday in advance of our next storm Saturday into Sunday.

Heavy rain this morning, break this afternoon

Hello everyone!

Today will feature heavy rain/freezing rain/sleet/snow in the morning tapering off this afternoon. Don’t get too excited though, mother nature comes back to bite with more precip this evening through tomorrow night.

The forecast looks good as I sample data from around the region this morning. It is thumping snow in the mountains and in the northern part of the state. 5″ has been reported at Sugarloaf Mountain for those lucky enough to be on the slopes today.

Cold air will drain south today at the surface which could cause some to go over to freezing rain. This freezing rain/rain line will creep southward as the day goes on. When precip redevelops tonight, the freezing rain will make it all the way to the coast.

Tomorrow morning, the late march sun will warm things up despite its lack of visual appearance resulting in the coast and inland areas going back to plain rain. The mountains will continue to stay all snow.

Precip continues through the day on Monday ending as snow for all Monday night. A coating is possible at best for the coast and adjacent inland areas. Precip comes to an end Tuesday morning between 3 and 6.

We have a lovely week ahead of us with mainly sunny conditions and warm temps in the 40’s. Tuesday will feature the passage of a front which will bring some extra clouds and the chance for a shower.

I know nobody wants to hear this, but another coastal storm looks to affect the region next weekend with more rain and mountain snow. As they say, April showers bring May flowers.

Rainy Sunday

Hello everyone!

Today will feature mostly cloudy skies and warm temps with highs rising well into the 40’s. Any rain from our approaching system should hold off until late afternoon for southwest areas and for everyone else, any precip arrives after dark.

Tonight, rain moves in and becomes steadier and heavier as our storm begins to develop. Expect light NE winds as this storm will not be very strong nor will it be intensifying all that fast.

Tomorrow features heavy rain and breezy conditions. Expect highs in the low 40’s. Rain should become lighter as the afternoon progresses but as I will explain below, precip could hang around until midweek.

Monday through Wednesday will feature light to moderate rain/freezing rain/snow even at the coast. I expect Sunday night into Monday morning to be the worst in terms of icy conditions.

Late week we clear out and warm up into the upper 40’s under sunny skies. More rain/freezing rain/snow is possible next weekend but there are still a lot of details to be worked out.

Keep in mind, the storm could stall far enough offshore to get sunny and upper 40’s starting Monday or Tuesday. This is a very finicky pattern so keep in mind that is a possibility though don’t expect it.-

As spring arrives and warm and cold air battle it out over the US, we often get low pressure systems that are ‘cut off’ from the rest of the jet stream. They will meander around extremely slowly (anyone could out-jog them fairly easily) while bringing rainy/snowy weather to whichever area they happen to be in.

This is the kind of setup we will be stuck with over the next 5 days. The low will stall off Cape Cod and sit there with no interest in moving an inch. As a result, prolonged periods of rain and freezing rain are expected. It looks like the mountains will be too far away to get any more snow but that is also a possibility just as no precip is.

Expect QPF (Quantitative precipitation forecast which is the amount of liquid forecast to fall from the sky. Usually 1″ of QPF is 12″ of snow) amounts around an inch for the mountains and between 2 and 3 inches at the coast. This will fall starting this afternoon into tonight and last until Tuesday or Wednesday.

I think that the majority of that will fall as rain for the coast but starting Sunday evening, a flip to freezing rain is likely. I expect freezing rain amounts to be between 1/4″ and 1/3″. I will go into more detail below.

Impact map 3-29

Zone 1: Heavy snow. Snowfall amounts between 12 and 18″ with 24″ amounts possible. Expect snow to start tonight and end tomorrow night. Winds out of the NE at 10-15 mph. Temps in the low 30’s.

Zone 2: Heavy snow with a little rain possible. Snowfall amounts between 6 and 12″ Expect snow to start tonight and end Monday. Winds out of the NE at 10-15 mph. Temps in the low to mid 30’s.

Zone 3: Rain/freezing rain with a little snow. Snowfall amounts between 2 and 6″. Freezing rain amounts between 1/4 and 1/3″ Expect snow to start tonight and change to snow tomorrow before turning back to snow Monday.  Precip ends Monday or Tuesday. Temps in the low to mid 30’s.

Zone 4: Rain with some freezing rain. Freezing rain amounts between 1/4 and 1/3″ Expect rain to start tonight and possibly extend through Wednesday. Rain amounts 2-3″. Temps in the 40’s tomorrow falling into the 30’s tomorrow night through Tuesday/Wednesday.

Zone 5: Rain. Rain amounts 1-3″ higher amounts in the NE sections. Along the Maine coast, freezing rain is possible Monday through Tuesday/Wednesday. Precip ends Tuesday/Wednesday.

I am concerned about flooding because there is a heck of a lot of water locked up in the snow in the foothills and mountains. In areas forecast to get 2-3″ of rain, up to 10″ is locked away in the snow. Not all 10″ will melt but there are sure to be problems with this kind of a setup.

SWE 3-29

This map shows how much water there is in the snow. Click to enlarge.

As hard as it is to believe, there are still ice jams on the rivers left over from the January thaw. When new water flow into rivers already ice-jammed, minor flooding is likely.

Most of the area is under a flood watch from the NWS with the exception of far northern areas which are under a winter storm watch.

After this storm, warm and mild conditions are locked in place as we sit under high pressure. However, all good thing must come to an end as wet weather threatens for next weekend.
