DISCUSSION

Key Message 1: Dry weather continues the remainder of this week and into the weekend with temperatures near to just below normal.

Another cool night is expected tonight as solid radiational cooling conditions setup with mostly clear skies and calm to light and variable winds. Lows are expected to dip into the mid 40s, though spots in the lower 40s cannot be ruled out.

Otherwise, another fairly rinse and repeat forecast is expected over the coming several days. As we head into the later part of the work week, a deep trough currently off the southern CA coast, will slowly work eastward into the Four Corners region, further amplifying the central CONUS ridge and troughing over the eastern US. While this upper level pattern should not bring any significant changes to the pattern we are currently in, high temperatures Friday and Saturday continue to trend cooler, toward the upper 60s to low 70s Friday and the mid to upper 60s Saturday. Late this weekend into early next week, temperatures likely return to near normal values again as global models show the ridge finally building overhead with surface high pressure working into the Carolinas. As discussed the past few days, the chance for meaningful rainfall remains very low into early next week with minimal moisture advection into the Southeast.

AVIATION /00Z THURSDAY THROUGH MONDAY/

Mainly VFR conditions likely through the next 24 hours.

Light and variable winds are generally expected to continue with broad high pressure to the northwest of the area. Winds generally favor a northerly direction, although likely remain at 5 knots or less for most of the period. While there was a marginal increase in low level moisture today, likely not sufficient enough for widespread restrictions overnight. Would not be surprised if a very brief period of visibility restrictions at AGS or OGB but probability generally remains low.

EXTENDED AVIATION OUTLOOK...Moisture creeps back into the area this weekend. Some patchy fog will be possible late in the extended.

CAE WATCHES/WARNINGS/ADVISORIES

SC...None. GA...None.
