SYNOPSIS
Chilly this morning, then turning comfortable and mostly sunny this afternoon. Cold front moves across southern New England on Wednesday with showers and perhaps isolated thunderstorms. Large high pressure will build into the region Thursday through Saturday bringing dry weather with moderating temperatures Friday and Saturday. The next chance of showers will be Saturday night into Sunday as a frontal system approaches. Much warmer temperatures are possible by Sunday/Monday but a backdoor front may keep much of the region cooler after all.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Highlights:

* Clear and chilly to start. Sunny and comfortable this afternoon.

Brr, a chilly start to the day thanks to clear sky cover overnight and calm winds. Frost Advisory remains in effect until 7am due to morning temperatures across portions of Connecticut and southeast Massachusetts, as well as Rhode Island. Temperatures will quickly climb into the low and middle 60s this afternoon, while the immediate coast remains in the upper 50s. Plenty of sunshine this afternoon due to a broad area of high pressure stretching across much of the eastern seaboard.

Due to the dry profile of the lower atmosphere could have issues with our dewpoint forecast today, did opt to use the 10th percentile of the NBM, but this might not be low enough - something the day shift will need to monitor. As it stands, the minimum value of relative humidity this afternoon is 20 to 30 percent. Winds are from the south this afternoon at 10 to 15 mph and gusts to 25 mph.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/
Highlights:

* Less cold Tuesday night, showers return for Wednesday and perhaps an isolated thunderstorm during the afternoon.

Overnight into Wednesday morning is less cold, due to the increasing cloud cover and steady southerly wind, temperatures only drop back into the upper 30s and low 40s. No threat for frost, but that does return Wednesday night - likely to result in a new frost headline.

Our next chance for rain and perhaps an isolated thunderstorm is Wednesday with the passage of a cold front and its associated robust mid-level shortwave/trough. There is adequate moisture, PWATs are between 0.7 and 1.0 inches, and lift to support numerous showers during Wednesday morning. Do think the better chance for any rumbles of thunder would be during the afternoon do the the steep mid-level lapse rates - in addition to a couple hundred units of surface based CAPE. QPF is in the neighborhood of 0.10 to 0.15 inch, but isolated areas of higher amounts are possible within these isolated thunderstorms.

Afternoon highs will depend a bit on the amount of clearing we have during the afternoon, but generally a seasonable temperatures in the upper 50s to low 60s. Behind the front, the wind becomes northwest and sets the stage for a much colder night ahead.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/
Key Points...

* Widespread showers Wed and possibly an isolated t-storm, then drying and cold Wed night with freezing temps.

* Dry Thu through Sat. Cool Thu then milder Fri-Sat

* Chance of showers Sat night and Sun

Details...

Dry, post frontal NW flow kicks in late Wednesday and persists into Thursday as high pressure expands from the Great Lakes into New England. This will lead to a colder airmass once again overspreading the region and lows in the upper 20s/low 30s Thursday morning.
Frost/Freeze headlines will likely be needed on Thursday and potentially Friday mornings. The surface high remains in control through Saturday, becoming centered over New England on Friday and sinking to our southeast by Saturday night. This pattern offers plenty of sun and light winds each day, so while relative humidities will be quite dry on Thursday (20-30%) fire conditions shouldn't be too elevated unless the high is slower to advance east (and breezy winds were to then linger into Thursday afternoon).

Our next chance of rain comes in the second half of the weekend as the high pressure is shunted southward by our next shortwave rounding the ridge. However, confidence is low for this portion of the forecast given the wide range of possible scenarios. For what it's worth, both the EPS and GEFS ensemble guidance have at least a 30% chance of measurable rain by Sunday afternoon, so odds of unsettled weather will be on the rise regardless. The biggest forecast challenge will be for high temperatures Sunday and Monday.
Guidance continues to advertise the chance for the warmest temps of the season so far (well into the 70s). However, the possibility of a backdoor cold front to keep much of our region colder looms large; this would result in a large gradient from eastern MA to southwest CT. GEFS ensemble guidance is less enthused with the widespread warmth than the EPS at this point. Stay tuned.
