Some Strong To Possibly Severe Thunderstorms Expected Late Monday Afternoon & Monday Evening

For The Rest Of Today: Any leftover shower activity should end around midday today with skies expected to be partly sunny during this afternoon. High temperatures this afternoon will be around 75 Degrees. In addition, it will be a little more humid as compared to yesterday, however, a south to southwest wind gusting up to 30 mph should offset this humidity somewhat.

Tonight: Some showers and possible thunderstorms will overspread western and central Mass starting around midnight and continuing during the after midnight hours of tonight. Low temperatures tonight will be around 60 Degrees with continued increasing humidity.

Some Strong To Severe Thunderstorms Are Expected Late Monday Afternoon & Monday Evening: A cold front is expected to push across southern New England during late Monday afternoon and Monday evening. Before then though, we may see some low clouds, fog and a couple of showers to begin the day before skies become partly sunny by late morning with partly sunny skies persisting into Monday afternoon. Because of this sunshine, temperatures by Monday afternoon will be around 80 Degrees or so with quite humid conditions.

Some of the ingredients for severe thunderstorm development are falling into place for late Monday afternoon and Monday evening across Western and Central Mass. The atmosphere is expected to be quite unstable during Monday afternoon with strong mid-level winds present. This means that if we do see any severe thunderstorms, the main threat will be damaging wind gusts. In addition, there is some potential for an isolated tornado, especially in areas where the low-level winds can become funneled such as the I-91 corridor and the I-395 & I-190 corridor in Worcester County.

With that said, there are quite a few ingredients that preclude severe weather. If the morning clouds and fog linger longer into the day, it would cut down on the amount of unstable air that is available. In addition, the highest amount of unstable air could actually occur further north across southern Vermont, southern New Hampshire and southwest Maine which could lead to a lower severe weather threat here in Western and Central Mass.

Here Is What Could Occur: Strong to severe thunderstorms may push eastward into Western Mass between 3 and 5 pm and begin to impact Central Mass during the 4 to 6 pm time frame. Some strong to severe thunderstorms may persist into Monday evening before coming to an end towards midnight.

Damaging wind gusts, frequent lightning and torrential downpours will be the main threat with any severe thunderstorms between 3 pm and 10 pm Monday. With that said, an isolated tornado or two is not out of the question, especially in areas where the low-level winds can locally shift into a south and southeasterly direction such as the I-91 corridor/Pioneer Valley region and the I-395 and I-190 corridor in Worcester County.

Needless to say, I will be keeping a very close eye on the weather for Monday afternoon and Monday evening and will keep you all updated.

Tuesday Through Thursday: We may actually see three consecutive days of dry weather across Western and Central Mass as an area of high pressure takes control.

Tuesday is expected to be a sunny to partly sunny day with very windy conditions for late May. High temperatures Tuesday will be near 65 Degrees. Northwest winds are expected to gust up to 35 to 45 mph at times during Tuesday.

Wednesday is expected to be sunny with high temperatures between 65 and 70 Degrees.

Thursday looks partly sunny with high temperatures around 70 Degrees.
