We have to get rid of this persistent trough

 We have to get rid of this persistent trough

The secondary cold front that came through later yesterday and last night, cleared the clouds out, allowing for great radiational cooling conditions leading to a very cold night, that provided frost and freeze for many of us.

Today will be the best day of this work week, as high pressure continues to work down out of Canada. Looking at the surface chart, radar and satellite. We can see not much is going on overhead, high pressure is providing plenty of sunshine, with only a few clouds leaving the region rain free.  Temperatures today will be seasonally cool but comfortable.  But this won’t last.

On Satellite we can see a strong shortwave up over the Upper Great Lakes. It also shows a lot of moisture over the Southeast. This shortwave will approach and move through Tuesday night and on Wednesday

A warm front will lift through Tuesday night into Wednesday, there could be some rain showers accompanying the front.  The upper-level low setup will keep us a bit unsettled.

Then the cold front will come through later Wednesday and Wednesday night.  Bringing more rain showers and thunderstorms. General rainfall amounts over the next few days, looks to be 0.50 to 1.0 inches.  Tomorrow we’re going to see an area of low pressure develop along the frontal boundary. We’re going to have high pressure over the Canadian Maritimes this is going to help suppress the low pressure to the south and west.

This will end up being cut off from the flow and hang out over Pennsylvania. This will be hanging around for Thursday, producing scattered rain showers and isolated thunderstorms. Some of those in southern New England into the Middle Atlantic could see with embedded moderate downpours at times.

The cutoff low will slowly start to pull away Thursday night and Friday providing isolated to scattered rain showers. On Friday the showers should be more in the way of lingering and spottier. Those with the best chance of see more in the way of steadier rain, will be closer to the coast and across southern parts of the Maine into Southern New England. After Friday we’ll see temperatures start to climb.

The first part of the weekend starts to be dry. But we will be watching a weakening cold front approach accompanying a little trough.  This will be moving across the region for later Saturday into Sunday. Right now, it looks to bring widespread clouds and the chance for isolated rain showers, but many of y’all shouldn’t see them.  This will be the start of a shift into a drier and warmer pattern.

But we could end up with a system and some showers and a few thunderstorms for Labor Day Monday as a warm front lifts into the region, with the front much milder air will work into the region.  On Tuesday the trailing cold front will slowly work through. Ahead of the front that southern flow will bring in even warmer air, but the air will be more humid that we’ve been seeing. The front will also bring widespread scattered rain showers and thunderstorms. Tuesday afternoon into Tuesday evening, some of these thunderstorms could be strong to severe.

Thank you for taking the time to read this.

Have a great rest of your day
