After a record setting week in March, April cooled off but still some pleasant weather to come. Temps will hover near the 50 mark Tuesday and wednesday with mid 50s Thursday and friday. The weekend will feature temps near the 60 mark. There is a slight chance of precip Wednesday but otherwise partly cloudy.
Stay tuned!

Wednesday – Wednesday night – Thursday – Thursday night will show us some winter here where last Fridays storm left us out. The farther south in ME you go the more snow you will get. 1′ is expected south of Auburn with 6″ towards Augusta and 1-3″ anywhere north of that.
A warm front will move north starting precip Wednesday. This front will stall and still produce precip while a upper trough (still binging precip) that will stall as well (still bringing precip) will trigger a secondary low that will partially stall (still bringing precip though this precip will be heavy) and rapidly develop bringing heavy precip. Next, adding to the cauldron of meteorological developments piling up almost as fast as the snow; another upper trough ( still bringing heavy snow) will nudge the existing upper trough, the warm front, and the coastal low into motion. A third upper level trough and a cold front will continue the snow into early Friday morning.
Stay tuned!

New radar updates filtering in now and the situation is clear. Definite spin with the original low and secondary low forming as well. The low has stalled and so precip will hold off until after dark. Second low will intensify as it moves NE and bring more stable accumulations with dropping temps. Snow will end near dawn Saturday in most areas excluding the mountains where upslope snow showers will continue to crank Saturday
Snow amounts
Coast south of Portland- Coating to 1″
Coast north of Portland – Bath excluding Yarmouth, Freeport and Falmouth 1-3″
5 Miles inland to 20 Miles inland including interior Casco Bay- 3-6″
20 miles inland to mountain zones 4-8″
Mountains- 10-14″
Strong coastal low developing rapidly with cyclogenisis occurring near 40N 70W as the low moves NE.
Updates will continue to flow in as the weather continues to progress.

3:45 pm EST Thursday 2/23/12: Snow will overspread the region Friday Morning and continue throughout the day peaking at around noon. Temps will hover near freezing or a little bit above throughout the day. Temps will sharply rise in the 500 hour when a warm front comes through. This will cause a change to rain up until maybe 5 miles from the immediate coast. This changeover will persist for an hour or 2 and then cooling takes place after dark returning snow for all. Snow will taper off and end at around 2-3am north to south. Clear skies return with blustery conditions saturday.
Friday will feature essentually a very stormy day. Rain at the immediate coast and snow in the mountains with mix in between.
Going in depth a little more… A low will intensify as it moves NE out of the Ohio valley and into New England Friday morning. Snow will overspread the region Thursday night and will stay snow across the entire forecast area untill ~8am. This is where the forecast becomes very tricky. The coast south of Portland will experiance the changeover first with rain overrunning that area and remaining locked in place as warm air pushes north. Meanwhile a secondary low undergoes cyclogenesis over Cape Cod. Depending on how strong this low gets, the warm air could stall or even retreat slightly.
There are 3 dominant senarios for the secondary low development: 1) 2nd low deepens more rapidly and pulls in significant cold air therefore resulting in more significant coastal snows. 2) 2nd low fizzles and gets absorbed by intensifying main low therefore pulling in little to no cold air resulting in minimal coastal snows and hevier upslope snow. 3) 2nd low deepens at a marginal rate resulting in a moderate amount of cold air being pulled in and causing the warm air to be bottled up resulting in a sharp coastal front with a steep temperature difference. The exact placement of this front will likely determine the rain snow line if senerio 3 plays out

Snow will be falling today in NE as a warm front pushes north. The warm front will bring warm air and this will cause a mix at the coast and some light rain tomorrow. After that the forecast really becomes extremely unclear. Models like the idea of a coastal storm developing Friday or Saturday with an extremely large trough digging down through the eastern third of the country. Models have been backing off on that solution however there is a possibility to see a storm develop Monday.

Models have been tracking a little bit farther west and that means rain for the coast as well as some freezing rain and snow at the very beginning. Snow/mix/freezing rain will all change over to rain around daybreak. Inland will see snoe changing to mix/freezing rain around midday and Te mountains will see mostly snow with occaionial sleet mixing in. Amounts will go as following: Southern coast as well as the immediate middcoast and southern interior-1-2″ inland and midcoast and foothills-3-6″ Mountains and North 4-8″.
Stay tuned!

Today a cold front moved through the area bringing in cooler temps for the week topping out wednesday in the mid to lower 30s for southern NH and southern ME 30s south into CT and 40s South to Philadelphia. 50s into VA and MD. Thursday will be similar and partly cloudy like wednesday. Friday will feature precipitation in northern NE but is a little early to go into details.
Stay tuned!

Wednesday 5:00: Forecasts have shifted dramatically this past week. Just 1 week ago the forecast was 50 and rain, now it is 33 and snow with freezing rain for Friday. There is some tricky parts in the forecast though. It looks like there will be a strong temperature difference between about 100 yards from the shore where the high will be around 32 or 33 and snow while even 100 yards offshore where highs will be in the upper 30s and rain. Amounts: islands and tips of peninsulas……………1-3″ Coast ( within about 1 mile of the water ) 4-6″ inland 8-12″ and mountains……………..7-9″. More updates in coming hours.
Stay tuned!!!
