Downpours Exit Northeast, Heat Humidity Next 4 Days July 4th Outlook
The process of transitioning into a very warm to hot weather pattern is just about done as downpours this morning are exiting to the northeast. We will see breaks of sunshine developing as we go through the day which will boost temperatures higher this afternoon. It may take awhile for the clouds to get out of the way north and east of NYC ( Southern New England and Long Island) and also there is the issue of a south wind holding temperatures back in the 70s here. But from NYC south and west we will reach up into the 80s. There is another chance for a pop up late day thunderstorm in one or two spots. Otherwise the rain is done for the most part.
Regional and local radars show the line of downpours with a warm front moving northeastward. Radars are quiet to the west and south.

Tonight will be a warm and humid night as skies clear with lows in the mid 60s to lower 70s. Then on Wednesday we have an upper trough approaching. Look for sunshine for most of the day with the chance for evening thunderstorms. Highs will be in the 80s to near 90. The upper trough will lower the humidity slightly for Thursday.
Thursday we will see sunshine, very warm to hot conditions, with humidity levels a bit lower. Highs will be in the 80s to near 90 degrees. Friday the humidity goes up a notch with sunshine and highs in the upper 80s to lower 90s. There is the chance for scattered thunderstorms Friday evening as another upper trough moves through.
Saturday beings a parade of cold fronts which means Saturday will be the last day of heat and humidity. Depending on how much sun it may be the hottest day of the stretch with highs reaching a range of upper 80s and lower 90s. A weak front approaches with some thunderstorms Saturday evening. Another front follows later Sunday as the upper flow turns northerly. This will be bringing down dry air from Canada once the fronts move through. Sunday look for a mix of sun and clouds with another shower or thunderstorm possible with highs in the 80s. Monday it will be nice and dry with sunshine and highs in the upper 70s to lower 90s.
If the weather map looks like the one above on Monday it will be very nice in the East Monday into Tuesday with low humidity reaching south into Virginia. Another front is forecast to approach for Wednesday so we may warm up into that but there could be another shot of dry and cooler air for the 4th of July and the end of next week. It is still an early call but the upper air pattern does favor dry air from Canada to come into the east every 3 or 4 days which will limit heat and humidity in the longer term. There is room for optimism going forward with no onshore flow issues or long duration rain events.
