SYNOPSIS
Dry and blustery conditions continue tonight into tomorrow with unseasonably chilly conditions. Dry with seasonable temperatures on Thursday. Quick shot of rain later on Friday into early Saturday. High pressure returns later on Saturday.
Another round of unsettled weather Sunday or early next week, but details are uncertain at this point.
NEAR TERM /THROUGH TONIGHT/
240PM Update
Tonight
Any remaining instability driven rain/snow showers taper off early this evening. Deep west/northwest flow continues to support strong CAA over southern New England tonight into Wednesday morning. This will allow 925 hPa temps to fall to between -8 and -10 Celsius.
While skies will be clear with a bone dry air mass in place, the gradient wind will support mechanical mixing that will prevent efficient radiational cooling overnight. Nonetheless, most location across southern New England will experience overnight low temperatures in the upper teens to low 20sF. Furthermore, with gusty west/northwest winds there will be a wind chill effect that will make temps feel closer to the low to mid teens.
SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/
Tomorrow
West/northwest winds begin to weaken and shift to west/southwest as a mid-level ridge axis builds east of southern New England. Air mass remains anomalously cold with persistent -8 Celsius temps at 925 hPa through tomorrow afternoon. This will keep afternoon high temperatures in the mid to upper 30s across most of southern New England with a few locations in southeastern MA and RI perhaps touching 40. PWATs less than 0.2 inches will limit any significant cloud cover aside from a few diurnally driven low to mid clouds, so despite the cold temperatures there will be plenty of sunshine tomorrow. Low-level jet will not be as robust as it was on Tuesday, so despite a well mixed boundary layer, we're only expecting a steady 10 to 15 mph west/southwest wind to prevail through tomorrow afternoon.
Tomorrow Night
Weather remains quiet tomorrow night. Southwest winds advect slightly warmer air into southern New England tomorrow night allowing for a slight uptick in overnight low temps in the low to mid 20s. West/southwest winds become more modest in the 5 to 10 mph range. Some hi-res model solutions are hinting at the potential for some ocean effect rain/snow showers over the outer Cape/Islands. Confidence too low to include any slight chance PoPs, but will be something to monitor over the next 12 to 24 hours.
LONG TERM /THURSDAY THROUGH MONDAY/
Highlights
* Temperatures generally near to slightly below normal
* Rain later on Fri into Sat with near to above normal temps.
* Turning drier Sat. Next shot for unsettled weather comes Sun and/or early next week.
Have average confidence in the details of the overall synoptic pattern into Friday. After then, confidence diminishes rapidly. The main synoptic features in the mid levels will be a near climatological minimum low over Hudson Bay, and broad longwave trough expected to develop late this week over the western USA. The evolution of this longwave trough as it moves into the central CONUS is fraught with uncertainty, especially with respect to timing.
Favored the NationalBlend for this weekend into early next week to take advantage of its ensembled approach.
At the surface, high pressure over the SE USA and northern tier of the USA will also play a role. The SE high pressure should move offshore late this week, opening the door for a low pressure traversing a front to shoot the gap between it and the northern high pressure. Looking like there should be a period of wet weather sometime Friday into Friday night. Another period of wet weather is anticipated sometime Saturday night into early next week. Given the timing uncertainties, maintained a broad period precipitation chances, but am not thinking it will be ongoing this entire time.
While temperatures are anticipated to be near to slightly below normal, thinking that they will be high enough to result in rainfall late this week. Some potential for some light snowfall across the higher elevations of interior southern New England, especially if the precipitation can fall at night. Too much uncertainty in the details to pin that down at this time.
Ensembled data depicts a rather gusty stretch, but not uncommon in southern New England for this time of year. Thinking one should be Thursday night into Friday as we get the squeeze play between the two surface high pressures. Another period could be sometime early next week as a coastal low pressure moves off the Mid Atlantic coast. These aspects of the forecast will need to be refined with later forecasts.
