As of early this morning, chillier, Canadian air is building into the region following the passage of a cold front last night Soundings reveal a good deal of dry air through the atmospheric profile… which would promote mainly sunny skies today; though, it will be a fight between downsloping low level flow and low level instability for extent of cloud cover, especially this afternoon.
High temperatures will generally be 10-15 degrees below normal for this time of the year as a protuberance of the polar vortex passes through northern New England Expect a near carbon copy of today, tomorrow; 850mb temperatures 1-3 degrees warmer across the region. Slightly less downsloping flow/atmospheric turbulence tomorrow… likely cancels out slightly warmer 850mb temperatures => surface high temperature slightly chillier than today. Abundant sunshine anticipated, though high temperatures again 10-15 below seasonal norm.
Surface high moves directly overhead on Tuesday before sliding east. This will allow for a chilly but light flow off the Chesapeake, making this day the coolest of the stretch!
On Wednesday, low pressure tracking through the upper Great Lakes will drape warm front down the spine of the Appalachians eastward into the Mid-Atlantic. Low-level moistening throughout the day promotes shower chance, especially later. Given setup, temperature should remain fairly level or even rise at night.
Cold front approaches/passes on Thursday, likely bringing a period of rain with it. Likely turns out to be a warm day… allowing for south to southwesterly flow Trailing upper energy moves through on Friday… at this point, looks like clouds/sun/iso. shower with slightly below seasonable temperatures; secondary wave on front passes well offshore Another front passes later next weekend or early during the week of the 30th likely ushering a very chilly airmass for the season/start of April.
