Western Mass Regional Weather for May 5, 2025

TODAY’S NUTSHELL: We continue to be stuck between a stalled upper low to our southwest, and a slowing high pressure area in Atlantic Canada. Both contribute to south-southeasterly ocean flow which will produce periods of showers at times today, with a chance for heavier rain tonight into Tuesday along with a thunderstorm. The upper low swings through Wednesday with more showers and storms accompanied by small hail/graupel. We then hope to get a break by Thursday followed by the potential for more rain Friday and Saturday with up to half a FOOT of rain possible for some by Saturday night, if the weekend storm sets up.

YOUR MORNING DISCUSSION

~~~~~~~~~~~~~~~~~~~~~~

Good morning folks, as mentioned in Today’s Nutshell, we will be under the influence of a blocking pattern that will keep southerly and southeasterly ocean flow.

This will send periods of rainfall our way from south to north or south-southeast to north-northwest today, tonight, tomorrow and tomorrow night.

While a bit less in terms of rain showers will move through today, another wave will bring heavier rainfall tonight into Tuesday, and that may be enough to cause some isolated flash flooding in east-facing high terrain of the western hilltowns.

Highs today will reach the 50s to low 60s, but a backdoor cold front may drop temps into the upper 40s to low 50s in SWNH, northern CMass and eastern Franklin County this afternoon. Patchy fog will also be possible, and easterly winds will gust 15-30mph today and tonight as ocean flow dominates our region.

Lows will drop to the 40s and low 50s tonight with increase in rain, heavy at times. Watch for street flooding and deeper puddles. Highs will be a bit warmer as a stationary front is brought north as a warm front with our overnight wave, and some thunder is possible tomorrow with highs in the low to mid 60s (lows will drop into the 50s with more showers and downpours).

On Wednesday, our upper low tracks northeast through our region, and with much colder air aloft, we will see periods of showers and thunderstorms, some with small hail or graupel mixed in. Highs will reach well into the 60s with lows either side of 50º.

Thursday may represent a break in the action, but a few showers will still be possible. After that little break, we’ll turn our attention to the Friday to Saturday timeframe when ANOTHER upper trough may dig into the eastern U.S. and setup another coastal low with more substantial rainfall into the greater WMass region.

If that happens, some of us could see upwards of 6” of rain, which could cause minor flooding on larger rivers, so I will be updating you on all of this as it transpires.

By next Sunday into Monday we may finally shake these upper lows and get some sunshine and warmth in here. Until then, more rain and clouds, I believe.


Have a great day!
