Transition Day Before The Mild
We have been talking about a weekend warm up but it is slow to get here. Strong high pressure off the coast is supplying the low level cold dense heavy air at the surface.. A huge upper level ridge in making for unseasonal warmth to build across the eastern US. As the high is pushing off the coast, it is beginning to wrap in slightly warm air with southerly winds as temps have been climbing into the 40’s this morning in the south, but the cold is holding strong across the north. The leading edge of this broad scale warmth across the east is overriding this low level cold air to form a deck of clouds across the region. These clouds will be around all morning into the early afternoon. As the warm front lifts farther north this afternoon, I expect the cloud deck to erode and give way to some partial sunshine with highs climbing into the 50’s and Lwr 60’s. The Warm spot will be in CT where there will be brighter skies. Temps will hold in the 50’s at the coast, where clouds could linger for much of the afternoon. Make sure to stop by and thank a Veteran at a parade today!
Clearing skies will continue this evening with lows holding in the lwr 40’s with light SSW wind. After a few clouds by dawn, Monday will turn into a gorgeous day with sunny to partly sunny skies, breezy SW winds will pump temps well into mid-upper 60’s. Clouds will likely begin to increase late in the day ahead of an approaching cold front. This front will push through Tuesday with showers. The high temps Tuesday will happen around sunrise in the 50’s. Breezy showers will keep it cool in the mid 50’s and then continue to fall through the afternoon with building cold high pressure to follow in behind. Steadiest showers will likely be during the morning hours, but could linger into the afternoon.
The unseasonal cool currently sitting over the Rockies where morning lows have ranged from 0-25 degrees….will begin to shift east and arrive behind this departing front Tuesday night. Cool high pressure will shift from the Midwest through the Ohio Valley then up through New England and take hold of our weather right into next weekend. This will mean days of sunshine, fair weather, and light winds. Great fall weather, but a little cool in the 40’s with a light persistent onshore NE wind.
