SYNOPSIS
Some freezing temperatures are possible tonight and early Tuesday morning across the northern and western Midlands. Dry weather and warmer temperatures follow during the middle of next week. Our next storm system is expected to develop across the southeast late in the week and bring increased chances of rain Friday and Saturday.
NEAR TERM /UNTIL 7 AM TUESDAY MORNING/
Batch of clouds continues to move through the northern Midlands and Pee Dee with much lower dewpoints moving into the western Midlands. Winds have also remained around 10 mph with gusts to 15 mph so temperatures have been a bit slower to fall however with the drier air temperatures will also begin falling.
Continue to expect overnight lows in the western counties will fall to freezing or below so the freeze warning will continue through early Tuesday morning. Elsewhere expect overnight lows generally in the mid 30s.
SHORT TERM /7 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/
After a cold start, deep northwest flow will build in at low levels and aloft Tuesday behind the sharp trough axis and will continue the strong cold-dry advection into the area. PWAT's will fall below 0.2" and cold advection will strongly mitigate any diurnal heating or downsloping, so temps will stay below average and top out right around 60F. Cold advection will steadily weaken overnight Tuesday into Wednesday, but winds will still prevent ideal cooling. So overnight lows will be noticeably warmer than Monday night. With little-no advection to speak of, downsloping flow and diurnal heating will help rapidly warm temps back into the 70's Wednesday afternoon. A very weak dry front is then expected to move across the area late Wednesday into Thursday as a low pressure system moves across the Ohio Valley. Moisture will be so limited that only some mid-level clouds are expected, but a marked wind shift from the northwest to east will occur by Thursday morning.
LONG TERM /THURSDAY THROUGH MONDAY/
Confidence is increasing overall in the long term period as a clearer picture for the SW CONUS trough is no evident in the GEFS and EC ensemble members. Thursday is generally a transition day, with fairly high confidence that we will remain warm and dry ahead of the approaching trough. As now seen in the GEFS and EC (both operational and ensembles), the SW Conus cutoff mid- level low will phase with some stronger southern stream flow and eject eastward Thursday. Strong warm-moist advection will occur ahead of the shortwave across our area by late Thursday night and throughout much of the day Friday. The ensemble solutions nearly universally show a widespread isentropic lift setup with a wedge-like surface ridge in place lee of the Appalachians, as PWAT's climb to around 150% of average. So a fairly classic setup for the region for a fairly prolonged light-moderate overrunning rain event. The trough then will push east and likely develop some sort of coastal low pressure into Saturday. Rainfall totals are still a bit uncertain but confidence is much higher in the PoP's than 24 hours ago. Drier and cooler air will fill in behind the coastal low late Saturday and Sunday.
AVIATION /00Z TUESDAY THROUGH SATURDAY/
High confidence in VFR conditions through the TAF period.
Skies continue to clear out as of 00z and are then expected to remain clear through the rest of the TAF period. West to northwest winds of 10-15 kts, gusting to 20-25 kts continue through about 06z before diminishing to generally less than 10 kts. Winds pick up again after 18z-19z, gusting to near 20 kts.
EXTENDED AVIATION OUTLOOK...Rain and associated restrictions possible Friday.
