Mild Air Holds On Before Midweek Changes
Mixed reviews on the weather this morning depending upon where you live. Clear skies, radiational cooling and light onshore winds allowed dense fog to form in spots overnight. The fog lifted quickly on the Cape to salvage the morning, but the Merrimack Valley and NW suburbs outside of Boston have had to deal with dense fog and low visibilites which will hang tough through midday. In fact fog from CT is expanding, despite the sun getting higher in the sky which is perplexing. I had a feeling there were going to be sneaky low clouds to deal with today and that is definitely the case.
With a warm front slowly lifting north today towards the NH border,…we will see Mixed skies with pockets of sunshine and and times of clouds. Light onshore winds from the SE will keep it cooler today in the 50’s to near 60. But Definitely no liking the visible satellite with low clouds converging and mid level clouds increasing from the west. Once fog lifts…The weather will improve through the afternoon into a pretty nice day. Clouds will continue to increase overnight with winds shifting to the South. This will make for a slightly warmer night in the 40’s with some patchy fog…likely not as dense.
Monday with feature breezy SW winds ahead of a cold front. Highs in the Lwr- mid 60’s with increasing cloudiness. Plenty of dry air at the low levels…along with the upper level ridge just offshore will keep the cold front from pushing too far into the region. Breaks of sun Monday…but clouds should win the day. Temps will average above normal Monday-Tuesday with thickening clouds.
The clouds will continue to lower and thicken with more of a SE wind on Tuesday. Still temps should remain mild in the lwr 60’s in southern new England. Light Showers will likely begin to break out ahead of the main batch of rain by Tuesday afternoon. With a low tracking into the Ohio Valley…rain will overspread the region from SW to NE Tuesday night with locally heavy rain into Early Wednesday morning before quickly departing. This will be a mild rain, but temps will be falling through the day Wednesday with cooler NW winds draining in cooler air on the backside.
A return to a more seasonal airmass for the end of the week with highs in the 40’s to near 50. Sunshine Thursday. Another upper level disturbance to swing through Friday afternoon/evening will bring in another cool shot of air to start the weekend…Mid 40’s for Highs Saturday with sunshine…before warming for the second half of the weekend.
Cooler times wait in the wings looking ahead into December…but the real cold will still be locked away through at least mid month…despite the periodic cool shot. Sometime around December 7th-8th we should get a good cold shot with a snow squall…but even that will lift out…with a seasonally cool airmass likely follow in behind through mid-December thanks to pretty flat flow to the jetstream. Cold enough for snow making…but snow storms? That will likely have to wait for now.
