Another Cold And Breezy Day

Hello everyone! 

Today will feature almost the exact same weather as yesterday with the exception being winds slightly less strong. Temps will still remain below freezing region wide with highs in the 20’s north and low 30’s south and winds will still be gusty though we’ll be in 20-30mph territory rather than 40-50mph territory in terms of gusts. 

Less cold air arrives tomorrow along with snow which could change to rain along the coast.

Cold And Blustery Today

Hello everyone! 

Today will feature partly to mostly sunny skies, morning snow showers/squalls, and afternoon blistery and cold weather. An Arctic cold front is driving SE across the area this morning and will be offshore by midday. Ahead of the front, snow showers and squalls are expected with impacts most pronounced in the mountains. Temps at the moment range from the low 20’s in the mountains to the low 30’s at the coast. Temps are expected to fall 10-15 degrees today despite the strong late March sun. This is due to a very cold airmass moving into the area on very strong NW winds. Gusts to 50mph are possible and as a result, wind advisories are up for the area through tonight when winds will die down a bit.

More Clouds But Still Mild Today 

Hello everyone!

Today will feature more clouds than sun for most as a weak front moves through. Ahead of the front, temps are expected to be pretty mild with highs ranging from 35 in the north to 50 in the south. The front will move through this evening with little fanfare though a few showers are possible this evening and  it will usher in cooler temps for tomorrow.

Continued Cool But Calm Weather

Hello everyone!

Today will feature a storm system passing well to our south-east and unfortunately too far out to sea to bring any meaningful snow though a few flakes could make their way to the coastline during the day. While we’re too far NW for the snow, we’re not too far NW for the clouds which will dominate the sky across southern areas. The mountains could get a peek or two of sun. Temps will range from a little below freezing in the north to a little above freezing in the south with a noticeable northerly breeze.

Still Cool But Quieter Today

Hello everyone!

Our blizzard is sadly long gone now and we’re left with cool temps and calm weather in its aftermath. Highs will range from 10 in the mountains to 25 at the coast with partly to mostly sunny skies and light NW breezes. A great day to make sure any remaining snow in driveways, walkways, porches, etc. is where it should be.

Lighter snow is possible Saturday before another shot of Arctic air arrives next week.

Great Cleanup Weather

Hello everyone!

After our beautiful storm yesterday, we have some calm weather today to clean up all that gorgeous snow. No more looking at bare ground and black snowbanks! Skies will range from partly cloudy in the mountains to super sunny along the coast with cool temps ranging from 15 north to 25 along the coast. Upslope snow showers will keep flakes in the air for the mountains and another couple of inches is possible there. A little upper level disturbance will pass overhead this evening with more snow showers possible then. Additional accumulations outside the mountains should be less than 1″.

More snow is on the way for the weekend!

Major Winter Storm Unfolds Today

Hello everyone!

Welcome to the “pre show” for our winter storm. Light snow is falling across much of the area and everyone should see flakes within the next hour or two. Light snow will gradually become moderate by mid day today before heavy bands begin to move in after lunchtime. Extremely heavy snow bands on the order of 2-6″/hour are forecast to move through during the afternoon and evening hours. Exactly where they linger the longest will determine who gets the most snow. During this time, winds will begin to gust into the 30-40mph range and whiteout conditions are certainly possible. Stay off the roads if you can at all help it. These snowfall rates are where plows struggle (or like our last storm are recalled off the roads for extremely dangerous conditions). Thundersnow is a distinct possibility in these bands as well.

As the storm progresses this evening into the early overnight hours, the dry slot will punch in bringing an end to widespread precip. However, instability within the dry slot will keep convective snow showers going (think hit or miss summer thunderstorms). These convective snow showers won’t last long in any one place but will be extremely heavy and carry with them the risk for thundersnow (again, think summer thunderstorms).

Here’s one model depiction of how the storm will play out. I like that it shows the transition between light/moderate snow this morning to very heavy snow this afternoon with snow hanging on until the lighter precip arrives in the evening. I’d be skeptical of the model bringing the mix all the way back into the mountains but an adjustment W from last night’s map is likely in order.

Updated Snowfall Map

Here’s a visual of that adjustment west with the mixing line. It’s possible some locations in the pink will see a few sleet pellets but it won’t meaningfully cut down on accumulations. I also expanded the up to 36″ zone because of the crazy intense dynamics and associated snowfall rates being reported to our SW across parts of NY, NJ, and PA.

This is likely my last update here for the day as I watch things play out. I’ll be geeking out over observations and satellite stuff over on my twitter feed @JackSillin as well as on the forums at 33andrain.com so check those out if you’re interested.

BTW, there’s more snow in the pipeline for the weekend. It could be another fairly sizeable storm for some but nowhere near the magnitude of this beast. More info on that after we take care of this one!
