Sunday Afternoon: Break then More Rain

Synopsis:

The upper-level low over NY will quickly exit to the east-northeast tonight. A 1000-mb mid-latitude cyclone in the lower Mississippi River Valley, powered by a deep short-wave trough, will head toward our area... arriving Monday night and leaving Thursday. High pressure settles in for Thursday and a cold front looms Friday.

Models Used: 09Z SREF, 12Z NAM, GFS, HI-RES NAM, 18Z RAP (HRRR); Confidence: Average

Short-Term:

UL low exits. Result: dry; otherwise, no change until Monday night.

Tuesday through Thursday: Showers.

Long Range:

Thanks to high pressure, we'll get some sun toward the end of the week before the cold front moves through.
