This is a short post to update the forecast for the rest of the holiday weekend.
Quick Forecast
Today: Partly sunny and hot inland. Slight chance of afternoon thunderstorms, some of which could be strong to severe. Highs in the upper 80s to low 90s inland. Highs in the upper 70s to low 80s at the shore. Chance of rain 30%.
Memorial Day: Rain, heavy at times. Highs in the mid to upper 70s. Chance of rain 100%.
Technical Discussion
Although we didn’t hit 90 on Friday to officially make this a heat wave, it has been HOT. Yesterday, Hartford hit 95 degrees. This is by far the warmest weather that we’ve seen since at least last year, and we have one more day of heat to contend with.
It is already a warm start to the day in Connecticut, with many spots already in the low to mid 70s!
The map above is also helpful for another reason—it shows where the backdoor cold front is. Remember that on Thursday, I said that Sunday would be a tough forecast due to the uncertain location of the backdoor cold front. This morning, I think the front just misses CT, meaning that inland areas will see a carbon copy of yesterday, with temperatures in the upper 80s to low 90s.
As for rain chances, I think we see isolated chances for storms, just like yesterday. Our short range guidance targets northern CT as the place most likely to see a pop up storm, but everyone should be generally prepared for a boomer, just as you would be during the middle of summer. It should be noted that with slightly better ingredients today, storms that pop up can be strong to severe. Western Mass is the favored location for storms.
Memorial Day
If you have outdoor plans in Connecticut on Monday, you may want to change them. Over the course of the weekend, the guidance has continued to show a very wet Monday.
The tradeoff is that temperatures will be kept at bay in the upper 70s, but the tropical moisture from Tropical Depression Bonnie and the shortwave to our west will make tomorrow a washout.
I should note that the radar depiction should be taken with a grain of salt. Where the heaviest rain sets up is still in doubt, and if we see the heaviest precip, there could be localized flooding.
Travelers should be cautious on the roads.
