Aviation updated. && .KEY MESSAGES... 1) Dry conditions through midweek, with rain chances late week. && .DISCUSSION... KEY MESSAGE 1: Dry conditions through midweek, with rain chances late week. A larger amplitude upper level shortwave trough is currently progressing across the Great Lakes region today. A cold front in association with this upper level trough is currently draped across central Indiana and northern Ohio, and is progged to push through the region during the overnight hours. Given the timing of the passage of the front, much of the area will remain dry, with only light showers possible for upslope locations across portions of SE West Virginia and SW Virginia. In the wake of this frontal passage, surface high pressure looks to settle across PA and NY, which will lead to drying across much of the area. While temperatures look to continue to remain elevated in the low to mid 80s across the mountains, and mid to upper 80s in the Piedmont, dewpoint temperatures look to drop into the mid 50s to low 60s across the area, which will make for much more comfortable weather across the region through the middle of this week. Temperatures remain elevated areawide primarily because upper level ridging looks to build in late Monday into the region as the aforementioned upper level shortwave ejects east of the area. Overall, the area looks to remain dry for much of the week, with a gradual return of surface dewpoints back into the low to mid 60s by Friday. Embedded upper level shortwave disturbances rounding the top of the upper level trough looks to bring low rain chances back into the forecast by Thursday for primarily mountain locations. The aforementioned upper level ridge looks to possibly break down by next weekend, with no significant rain chances expected prior to this. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... Widespread VFR conditions present across the region this evening. Only a few, light isolated showers in the Foothills this afternoon, but were very brief. Could see a few more isolated showers in central VA through this evening, but doesn`t look like any will impact any of the area terminals. Low stratus will build against the mountains late tonight and into the early morning hours as a front crosses the area. KBLF and KLWB will likely see the lowest ceilings, below 1kft, and KBCB seeing MVFR cigs. Patchy fog will also develop in the valleys tonight, mainly KLWB and possibly KBLF. This should dissipate by 14Z Monday morning with the arrival of drier air behind the front. After that, skies will be mostly clear for the TAF period. Winds will turn northerly Monday behind the front, but remain 10 knots or less, with an occasional gust to 15 knots or so over the mountains. Forecast confidence is high. EXTENDED AVIATION OUTLOOK... Mainly VFR expected through midweek, outside of any late night fog at the usual places like LWB/BCB. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
