A Few Strong To Severe Thunderstorms & Heavy Rainfall With Localized Urban & Poor Drainage Flooding Between 3 pm This Afternoon & 10 pm This Evening: A cold front is expected to slowly push southward from northern New England towards our area throughout today. At the same time this is happening, the moisture from the remnants of Barry will begin to move through our area.
This means that we will see two rounds of shower and thunderstorm activity today:
Round number 1 will be the rest of this morning with anywhere from a couple to a few showers and thunderstorms expected over the next couple of hours with this activity ending by midday.
A break in the shower and thunderstorm activity is expected from about midday until about mid-afternoon and in fact some sunshine is possible during the midday to 3 pm time frame. This will cause temperatures to climb into the upper 80s along with oppressive amounts of humidity.
Shower and thunderstorm round number 2 is expected to overspread Western and Central Mass beginning around 3 pm or so this afternoon in the form of widespread showers and thunderstorms. A few of these thunderstorms are likely to be strong to severe with strong wind gusts, frequent lightning and heavy downpours with localized urban and poor drainage flooding a threat. The threat for a few strong to severe thunderstorms is expected from about 3 pm this afternoon until about 10 pm or so this evening.
As I already mentioned, it will be very humid the rest of today with afternoon high temperatures in the upper 80s to possibly near 90 Degrees. Heat index readings could be between 95 and 100 Degrees this afternoon.
Late Tonight Through Thursday: That cold front will make its push through Southern New England during tonight and Thursday. This, combined, with the moisture from the remnants of Barry, will lead to widespread heavy showers and a thunderstorm or two throughout much of tonight and much of the day on Thursday. Heavy downpours with street and poor drainage flooding is likely tonight and Thursday across Western and Central Mass.
Total rainfall amounts by the time the rain ends late Thursday will range from between one half of an inch to one inch of rainfall from northern Worcester County to the upper Pioneer Valley to upwards of 1 to 2 inches of rainfall from southern Worcester County to the lower Pioneer Valley. Upwards of 2 to 3 inches of rainfall is possible across northern and eastern Connecticut.
Low temperatures tonight will be near 70 Degrees. High temperatures Thursday will be around 75 Degrees.
Friday: Some morning clouds will give way to partly sunny, hot and humid conditions by Friday afternoon. High temperatures Friday will be around 90 Degrees with heat index readings of near 100 Degrees during the afternoon.
A Very Hot & Humid Weekend Is Expected: A sunny, but very hot and humid day is expected on Saturday. High temperatures Saturday will be between 95 and 100 Degrees. Heat index readings Saturday afternoon will be upwards of 105 to 110 Degrees.
Sunday is expected to be partly sunny, very hot and humid. There may be a couple of showers and thunderstorms around late in the afternoon and evening Sunday. High temperatures Sunday will be between 90 and 95 Degrees. Heat index readings Sunday afternoon will be around 100 Degrees.
