It’s going to be a rainy start to your Wednesday with heavy downpours. The rain will slowly taper from northwest to southeast throughout the afternoon with a slim chance of an isolated afternoon storm (southeast) as a cold front heads offshore. It’ll be a very humid day with highs temperatures reaching the lower 80s. A High Surf Advisory for the South Coast/Cape/Islands is in effect until 6pm Thursday due to high surf (5-8 ft.), rip currents, and beach erosion. Most likely, these coastal concerns will be around through early next week due ot the path of ‘Leslie’.
Skies will begin to clear out tonight. Lows will be in the lower to middle 60s as dewpoints also drop back to the 60s.
Thursday will be a partly cloudy day with slightly lower humidity. Highs will be in the lower 80s. There will be about a 20% chance of a spot afternoon storm north and west of Boston.
Friday will be the result of a weak cold front moving through. Skies will be partly sunny with a chance of a few afternoon showers and storms. Highs will be climbing into the middle and upper 80s.
Saturday will be a dry day with showers and storms nearing New England late in the day. The rain appears to hold off until after sundown on Saturday. Highs will be in the lower 80s.
Sunday will be cloudy with scattered rain along with high temps in the 75-80F range.
Once the cold front swings offshore, we will have a break in the heat and humidity early next week. Highs will be in the 70s with dewpoints dropping back into the 50s.
Tropical Update: T.S. Leslie is expected to become a hurricane before the weekend arrives. The current forecast track has it passing just west of Bermuda and keeps it offshore into early next week. It will make its closest pass to Southern New England on Monday. This track needs to be watched closely. Luckily at the moment, both the GFSx and the EURO models keep the storm offshore although the EURO brings it a touch closer. T.S. Michael is not a threat to the U.S. as it veers to the north and northeast.
