WEATHER UPDATE 9:30 PM

Last Updated

Tonight’s early NAM data just became available. Little has changed from my earlier post.

Precipitation starts later, now between 11-1PM on Thursday (earlier south of the city).

Precipitation will be principally sleet, then rain.  There may be some snowflakes at the beginning, but this is a sleet—> rain event.

Temperatures during the day hover near and above freezing, then low to mid 30s.  Temperatures rise near 40 late Thursday night.

It will become windy late afternoon into the night.

Rain will be heavy in the afternoon and evening.  QPF values are 1-1.5 inches, mostly falling as rain.

The upper atmosphere chills before daybreak on Friday as the upper low merges with the coastal storm. Some snow may mix with rain briefly before daybreak Friday and before ending early morning.
