Weekend Update: Rainstorm on Tap

Good evening. I wanted to update blog due to a pending rainstorm that will hit the area Saturday afternoon into Sunday morning. In its wake, expect unstable conditions for at least the first half of next week with multiple chances at showers. This is all due to an unsettled pattern involving tropical moisture being sent into the area over a period of days.

Starting with tomorrow rain will move in by mid afternoon as a coastal low develops. This is pretty interesting because this is usually something we would see in the fall not mid July...

By the evening, it is raining stead in many areas with gusty winds...

The storm clears in the early hours of Sunday morning...

We are then left with mostly cloudy skies Sunday with the chance of a few showers. This is a big wildcard day as models are a little variable with how much rain they show. There is a chance the day can be salvageable.


Moving on , more rain comes on Monday as waves of tropical moisture cause showers over the area...

The next image below shows the moisture in green...notice the flow off the Atlantic right into our region as seen by the green shades...

This will cause this pattern to persist for a few days, pretty remarkable.

Moving back to Saturday, the upper level pattern intrigues me as it looks like an impressive winter storm with an upper level low to the west  over Ohio valley and a surface low on the coast...

IF only this was January.....

The next image shows how our trough of low pressure (blue) is squeezed between two ridges of high pressure out in the Atlantic and to the west. This is what is allowing the onshore flow of tropical moisture and days of unsettled weather...

Thats all for now, more to come on Monday.
