Barely any diurnal range anywhere on this continent. The noon temp map looks like the midnight one:
In late fall and early winter, near the solstice, there often is little diurnal pattern to temperatures. Otherwise the poles' temperatures would plunge six months in a row.
I suppose I'll have to keep an eye out for some flurries today.
The way this winter has been going, this may be our only chance for snow the whole winter.
At least, the pattern change seems to be a cold Midwest and less hot Southeast, but nothing particularly good as far as snow goes. But whatever happens, January and February will almost certainly be colder than December, which is a nice thought.
.NEAR TERM /THROUGH TONIGHT/...
AS OF 920 AM MONDAY...
MINOR ADJUSTMENTS MADE THIS MORNING TO POP/SKY CONFIGURATIONS TO
ACCOUNT FOR PATCHY FLURRIES/SPRINKLES THIS AFTERNOON. THE BACKDOOR
COLD FRONT IS CURRENTLY PUSHING SOUTHWARD THROUGH VA ON PACE TO DROP
THROUGH NC LATE MORNING INTO THIS AFTERNOON... AHEAD OF A RAPIDLY
DEEPENING VORTICITY MAX THAT WILL SWING SE THROUGH VA AND NRN/ERN NC
LATER TODAY. RECENT RUNS OF SEVERAL HI-RES MODELS BRING SPOTTY
CONVECTION SSE THROUGH THE HEART OF CENTRAL NC THIS AFTERNOON... AND
THIS UNIFORMITY AND CONSISTENCY BUOYS CONFIDENCE IN THE DEVELOPMENT
OF SHALLOW VERY LIGHT SHOWERS WITH ONSET OF MIXING AND THE APPROACH
OF THE FRONT AND INTENSE HEIGHT FALLS. FORECAST SOUNDINGS FROM THE
HRRR AS WELL AS LARGE SCALE MODELS SHOW WELL THE SHALLOW NATURE OF
SUCH CONVECTION TODAY CAPPED BY DRY AIR ALOFT... AND THE DEEP MIXING
AND FAIRLY HIGH CLOUD BASES SHOULD KEEP THE CHANCE OF ANYTHING
MEASURABLE QUITE LOW... UNDER 14% THROUGHOUT TODAY. BASED ON THE
PREDICTED SURFACE WET BULB TEMPS... THE LOW LEVEL THERMAL PROFILE
APPROACHING DRY ADIABATIC... AND THE VERY COLD AIR NEAR THE TOP OF
THE MIXED LAYER SUPPORTING A HIGH CHANCE OF ICE IN THE CLOUDS... WHATEVER FALLS SHOULD BE MOSTLY FLURRIES NORTH OF HIGHWAY 64 WITH A
FLURRY/SPRINKLE MIX SOUTH OF HERE AS WE HEAD INTO MID-LATE
AFTERNOON. STILL ANTICIPATE SUSTAINED WINDS INCREASING TO AROUND 10-
15 MPH WITH GUSTS AS HIGH AS 20-25 MPH BY MIDDAY AS HEATING DEEPENS
THE MIXED DEPTH. HI-RES GUIDANCE AND LATEST TRENDS SUPPORT HIGHS
FROM THE UPPER 30S NEAR THE VA BORDER (ONLY A FEW DEGREES ABOVE
CURRENT READINGS GIVEN THE INCOMING CLOUDS AND COLD AIR ADVECTION) TO THE MID 40S SOUTH. -GIH
12z GFS has ORD clocking a low of 1F which means most of the suburbs may well be below 0F
When is this for? I don't see any lows above 70 F for the next fifteen days.
