Not As Warm…But Still Nice
Another frosty morning in the suburbs of Boston. Another morning where the hills are warmer than the valleys with a morning inversion in place. Just like yesterday, warmer air aloft will allow a rapid warm up into the midday with temperatures quickly climbing into the 50′s this afternoon with Sunny to Partly Sunny skies.
Obviously, today will not be as warm as the balmy weather yesterday. Highs climbed to 65-70 through the Merrimack Valley and Southern New Hampshire. A backdoor front has pushed through and a cooler more seasonal airmass has followed in behind it. Our water temperatures are near 50 degrees, so a NE wind off the water will help to keep the coast in the Lwr 50′s while inland there will be a better chance to climb to near 55 this afternoon.
High clouds are streaming through this morning, but thicker stratocumulus clouds will back into New England off the water by the mid-late afternoon. These clouds will begin to thicken this evening with the chance of drizzle and fog starting to form by dawn with lows holding steady in the 40′s
Our backdoor cold front will try to move north as a warm front tomorrow. Pockets of drizzle and mist can be expected for the morning commute tomorrow with the warm front stalled right over us. Cool onshore winds out of the SE will help to keep the clouds locked in for much of the day…but the clouds may begin to break late for a few sunny breaks late in the day. a cold front will be pushing through New England at that time. SW winds aloft up the eastern seasboard will help to slow the front which will stall just off the coast.
We continue to track our next wave of rain which will be coming out of the Gulf and be directed right up the eastern seaboard. The low will track right up through the Appalachian Mountains and through New England Wednesday. The best chance of rain will be Tuesday Night and Wednesday morning…with the potential for .50-1.5″ of rain to fall by Wednesday afternoon.
The disturbance/clipper coming out of Canada we were tracking for Thursday does not look nearly as pronounced this morning…as it did yesterday at this time. In fact it looks like a simple frontal passage which will come with a few clouds and cooler air to end out the week with a reinforcement of NW winds which will help to keep temps in the 40s to end the week. The trend towards the cool will likely continue for a while as we start the transition towards the cooler season. Temperature contrasts in this transition will likely allow for an active pattern heading towards Thanksgiving and beyond.
