How can you top the weather from the past few days? Temps in the 80s, low humidity, tons o’ sun. It was as close to perfect as you can get for a Long Island summer weekend. All good things must come to an end as thermometers will rise and storms are on their way.
The humidity is on the increase since Sunday as dewpoints headed northward into the 60s overnight. With high pressure in control and moving offshore, the southwest winds will also affect temperature as they head through the 80s for highs Monday and Tuesday. The high will continue to move offshore, allowing a cold front to approach from the Plains and Great Lakes, the same front that caused severe weather in Minneapolis Sunday night. This will bring storms into the forecast and into the region as we head into the late day hours on Tuesday. Behind the front, more seasonable weather with low humidity and this looks to finish out the week.
Timing on the storms has been iffy. Taking a look at some of the computer models, there’s some disjointed solutions. There is a chance of showers and a rumble of thunder overnight into Tuesday morning, thanks to a pre-frontal trough. This may take away some of the fire that the cold front is looking forward to, meaning late Tuesday may not have much storminess if Monday night is active.
Wednesday through Friday is looking great with highs in the low 80s and low humidity as high pressure builds in.
