I’m a third-year atmospheric science student at Cornell University who has been blogging about the weather since 2011. While I’m not officially a meteorologist, I have accumulated a bit of experience forecasting both local weather (in western Maine and New Hampshire) as well as national/international weather during my time writing for weather.us and weathermodels.com. I also have experience programming in Python, teaching concepts in weather forecasting, and communicating forecast information to general audiences.

Wild temps while little precip

WILD March temperatures with readings peaking over 80 on sunday and a still mild start to the week.Temps Thursday will peak well into the 80s in some inland spots with low 80s at the coast. 70s Tuesday and Wednesday with sun all the way through the week. Friday will feature temps in the 70s.

Stay Tuned!

Wild temperatures

30s to start the week then 60s and 50s! The craziest part is that this is March! Heres how the next week stacks out in temperatures-  Fri-47  Sat-37  Sun-52  Mon-61   Tues-63 Wen-47  Thurs-48  Precipitation will occur Tuesday in the form of rain and there is a chance of minor coastal snow Friday night. Accumulations if any should be light.

Stay tuned!

Cool start to the week warmer temps by thursday

A cold front swept through last night leaving up to 5″ in the heavy snow bands. This will allow for high pressure and colder temperatures to dominate Monday and Tuesday. Wednesday the high will shift offshore bringing a warm flow with rebounding temps. 50s Wednesday and 60 thursday.

Stay tuned!

Mid-Storm update

Heavy snows spreading across the area now in bands bringing good accumulations piling up very efficiently. On that note I will need to update the snow totals for SW ME to 10-16″ due to a more northerly trend in the latest model run. Also need to say that winds have been picking up and will be peaking shortly. Winds will average 20 mph gusts around 30 out of the NE. Peak winds will be found at the coast.

Stay tuned!

Quick update on Powerful Thursday storm

New updates coming in recently showing more snow with amounts on the order of 9-15″ for York and Cumberland counties, 6-10″ for midcoast ME and most of central ME and Oxford county. 3-6″ N of Bangor and 1-3″ in northern ME

Stay Tuned!

Snow storm Thursday

A powerful winter storm is preparing to slam the region with heavy snow as well as some wind though the snow will really grab headlines. 8-12″ are expected in Cumberland and York Counties in ME and most of SW NH as well. 3-6″ in northern NH and in ME North to Augusta. 1-3″ in northern ME.

A powerful low will extend a warm front ahead of its move SE under a powerful high. This will bring a good steady snow and efficient accumulation. see other post for more in-depth analysis.

Stay tuned!

Thursday snow

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!

Thursday snow storm

Thursday will likely be our last chance at a very significant snowfall. A low will be moving out of the Great Lakes and will be nudged south by a fairly strong high in southern Quebec. This is a very cold high spilling cold air over the region so precipitation type will not be an issue with the exception of maybe Kittery where the warm air will be located. Confidence is still low so stay tuned for more updates.

Quick update

Snow has arrived and will remain entrenched through the night. Cyclogenisis has begun and 2-4″ per hour snowfall rates will be common inland ( 15 miles inland from the coast.) and 3″ per hour rates at the coast though inefficient accumulation will lead to lesser totals. Thunder will be likely at the peak intensification time ( 10pm-2am)

Snow amounts stay the same.

Update #3

4:15pm EST Friday 2-24-12

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.
