Lows this morning dropped to as low as -3. We saw 7 at the Purdue Airport. The Purdue Ag Farm dropped to 6, while we saw 7 at the WLFI ob site. The Purdue Ag Throckmorton station (north of Romney) dropped to 4.
This, before rising with south-southeast wind kicking in.
I cut lows back tonight from 20-27 to 12-21 due to less wind projected.
With mostly clear skies, patchy to areas of freezing fog are likely with heavy frost. A few patches of black ice are possible, as well.
We should turn mostly cloudy to cloudy Friday with highs in the 30s to around 40 with a south-southwest wind at 8-17 mph.
Fog will burn off, but it should be hazy through the day.
A few patches of drizzle to light freezing drizzle are possible late Friday evening-early Friday night with temperatures at that time 32-35.
Some patchy freezing fog may follow with lows 23-29.
Saturday looks mostly cloudy to cloudy with highs 36-42. It is possible that some fog may hang on in the southern part of the area into the early afternoon.
Winds will be south at 8-15 mph.
Sunday may feature fog with some patchy freezing drizzle early, then mostly cloudy skies with a high of 41-46 with southerly winds at 10-15 mph.
Monday may actually turn partly cloudy with southerly winds & highs 44-51 after some freezing fog in the morning possible.
CHRISTMAS EVE-CHRISTMAS DAY.............
Skies look mostly cloudy Tuesday with a southeast wind & highs 42-47.
Christmas looks mostly cloudy to cloudy with some showers late with highs 44-49. Winds look south-southwest at 10-20 mph.
Cold front should bring showers Wednesday night to early Thursday morning, followed by mostly cloudy to cloudy skies Thursday with north to northeast wind 10-20 mph. Highs should run at 35-40, but temperatures may fall a bit in the afternoon to 33-37.
NEXT THURSDAY NIGHT-SUNDAY.........
There are around three waves of precipitation forecast Friday night-Sunday with breaks in-between.
Since we may be near/north of the front Friday night to Saturday morning, it appears that the precipitation may fall as snow &/or mix (temperatures 28-32).
A shortwave may eject out from core of bowling ball upper level low on Saturday PM-night.
This may fall as rain, snow & ice in the area with mix & ice in the north & rain south.
It could be a very sharp temperature gradient over the area from 32 to 50 to 50s north to far south.
Best chance of snow/ice is along & north of US 24 at the moment.
Rain is likely late Saturday night to early Sunday (some ice north), but change-over to snow may occur area-wide Sunday.
Wind may really pick up with north to northwest gusts to 40 mph with the snow.
Some accumulation of the snow/ice is possible in these rounds, but it is a very tricky forecast with the warm front & the exact track of the upper low.
Just be aware of rain, snow, ice in various parts of the are Friday night-Sunday with accumulation possible at times in parts of the area.
It is a tug-of-war between Arctic high to the north & warm upper ridge to the Southeast.
Colder weather will follow overall.
Storm out of Texas may bring snow &/or mix in the first 10 days of January (after what could be brief clipper with some light snow).
Another big bowling bowl of low pressure from northern Mexico will make it to Texas & then should pivot northeastward. This could bring snow or mix to the area in mid-January.
There are three shots of brutally cold air in the January 16-24 time frame. The worst is trending toward January 22-24 with potential lows to -21 in parts of the area.
A widespread, solid snowpack is likely to be in place when this frigid air settles in & the snow depth will only enhance it.
