.SYNOPSIS…
The short-lived period of above-average temperatures comes to an end with passage of a weak cold front today. The next chance of precipitation will roll into the region late on Friday in the west, to early Saturday in the far eastern zones. The Blue-White Game will be sloppy with a steady rain, which looks to last into early Sunday. Temperatures look to moderate in dry conditions into the early work week, with hints of a return to warmth by midweek.
.SHORT RANGE…
Cold front currently sinking southward; as of 22z, progress just reaching I-80 corridor…front showing signs stalling out, so southern part of state will likely not drop as far tonight. Slt chance of –SHRA as moisture slides into general upslope flow…Light echos showing up on UNV radar already, but don't expect anything more than a brief sprinkle. CLDs and CAD will keep temps significantly lower during the afternoon tomorrow.
.LONG RANGE…
Massive storm system in Midwest currently producing tornadoes in OK and +SN in CO will move NE into the Great Lakes region this wknd. Models in fairly good agreement with ~15z arrival time or first precip into central PA, and appear fairly well initialized with current system placement, so tended to go with average model output. Very high PWAT anomalies and high low-level RH values lead us to expect extended period of steady RA Saturday afternoon. Lots of factors pointing toward 1"+ totals for much of state, with up to a couple inches possible in mtns. Can't rule out some snowflakes in NC zones early Sat. Windy conditions also expected as mixing may tap developing LLJ, creating gusty winds.
