Weekend Storm Lining Up

We're tracking another large storm system that will impact the middle of the country this weekend.  Right now the components to this system are in the Pacific Northwest or just further off shore.



As you've noticed the last couple of days, mild air is in place and the storm track has been consistently putting the local area on the warmer side of the storm, meaning primarily rain.  Note the placements of the center of the storm on the image above.

With a storm of this magnitude... a wide array of weather types will be felt across the country.  To our southeast, especially on Sunday, there's a threat of severe weather in the Ohio River Valley down into Arkansas.

On the northern side, especially towards the Dakotas, temperatures will be cool enough for snow to form.

Locally, expect periods of rain through the weekend, but there will also be a pronounced break Saturday evening as we get in on a fetch of drier air.  It's short lived though and a second wave of rain will enter early Sunday morning. 

As the storm passes to the northeast around midday Sunday, the gates will open for a breezy, cold wind to enter.  Temperatures begin to fall during the afternoon behind the a cold front.  Pictured below is temperatures and surface pressure for 3pm Sunday.

By the last couple of minutes of Sunday, temperatures will be ending up near the freezing point.

This means any lingering rain on the back side will likely come in the form of snowflakes for late Sunday evening into Sunday night.  However, at this point, any snowflakes appear to be minimal due to timing differences in when the cooler temperatures arrive and when the rain exits.  Precipitation and Temperatures shown for midnight Monday morning are below.




As far as rain amounts, early indications are pointing to at least 1/2" in the two day stretch, as much as 1" is possible.


Forecast:

Friday: Partly to mostly sunny.  Highs around 50°.  Wind: S 5-10 mph.

Saturday: Mostly cloudy, with rain likely.  A clap of thunder possible. Highs in the lower 50s.  Breezy.

Sunday: Mostly cloudy, with a chance for rain.  Changeover to snow possible late. Highs in the upper 40s early, falling throughout the afternoon/evening.  Breezy.
