Colder weather by Saturday night

Models haven’t changed much since yesterday.  GFS is really playing down the snow for tomorrow while the NAM is still hinting at about 2″ along and north of the Ohio River.  The NAM was better last weekend, but that was unusual.  Both models have continued to lower their rain predictions with which I agree.  So, here’s my latest thinking…

Saturday

Rain moves in before daybreak and continues through about midday.  During the afternoon rain will diminish to light rain/drizzle.  Rain may even quit for a few hours.  Temperatures will likely reach the mid 40’s.  Rainfall totals should be in the .50″ to 1.25″ range – most of Louisville area will be an inch or less with the heavier totals south and east of us.

Saturday night

Around 6-7 P.M.  the cold air will make its entry.  Temperatures will drop quickly and drop below freezing by 9-10 P.M.  – on their way to near 20 by morning.  Winds will be very strong overnight with gusts over 30 mph.

The cold air will bring some moisture with it.  A quick rain to snow changeover will happen during the early evening.  Any snow should move out of the area before midnight.  There won’t be much snow – probably an inch or less.  But, over the years we’ve certainly learned that even a small amount of snow can create big road problems. Some icy spots are likely on area roads tomorrow night.

Sunday plus

Winds gradually diminish during the day, but it’ll still be a cloudy, cold day with temperatures remaining in the lower 20’s during the day.  Monday morning lows in the city will be in the low to mid teens, slightly colder in rural areas.
