DISCUSSION
Key Message 1: Dry weather continues this week with gradually warming temperatures through Saturday.
The current temperature forecast is on track tonight as temperatures are currently in the upper 40s to mid-50s across the Midlands and CSRA. Temperatures at daybreak should be in the upper 30s to lower 40s in most spots. However, a few of the typically cooler locations could dip into the mid to upper 30s. Although the coolest of spots could see patchy frost, it should not be widespread enough that a Frost Advisory would be warranted tonight.
Minimal change in the overall forecast thinking with the extended dry period most likely continuing through the end of the month. Upper ridge will slowly translate east through the week and flatten out by Thursday, while surface high pressure remains anchored over the northeast and ridges south across the eastern seaboard. This will result in slightly warmer temperatures each day with fairly high confidence given very small NBM IQRs through Saturday, so expect a continuation of warm days and cool nights this week. Temperatures should reach above normal values by Friday and Saturday as the pattern starts to show some signs of shifting, with the next chance of rain returning to the forecast for the first day of November.
AVIATION /03Z TUESDAY THROUGH SATURDAY/
VFR conditions expected to continue through the TAF period.
Calm and clear condtions at all sites currently. FEW to SCT cirrus should move in into the overnight with light winds that continue into Tuesday morning. No fog is expected again tonight with dry conditions continuing. By the mid morning Tuesday, mostly clear skies and light winds out of the northeast are expected, continuing through the end of the TAF period.
EXTENDED AVIATION OUTLOOK...No significant aviation concerns through the week. A few to scattered high VFR clouds may move in Wednesday and Thursday due to onshore flow, but otherwise remaining dry.
CAE WATCHES/WARNINGS/ADVISORIES
SC...None. GA...None.
