SYNOPSIS.
High pressure over the Great Lakes region will continue the dry weather trend over the next several days. Gusty northwesterly winds are expected to continue through Saturday before diminishing on Sunday as the high slowly shifts southward; becoming more concentrated over the region by early next week. The high will then shift offshore; inducing a warming trend through the middle of next week.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/.
This mornings cold front has moved well south of the CWA; resulting in continued dry conditions under a gusty NW flow. Some scattered strato-cu persist mainly across eastern WV, northern MD, and northern VA and should diminish into this evening.Seasonable temperatures this afternoon; ranging in the upper 40s to low 50s across our southernmost areas. However it will remain much colder across the higher elevations over the Alleghenies with temperatures in the 30s. NW winds will range between 20-30 mph. Hi-res guidance, coupled with the rest of the 12Z suite continued to indicate gusty NW flow continuing into the overnight hours across much of the CWA, which will cause frigid overnight conditions with temperatures in the 20s for most with teens in the mountains.
SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/.
A large H5 low over eastern Canada will continue to retrograde inducing a large upper level trough that extends down to the southeast CONUS. Meanwhile upper level ridging persists over the Midwest which will result in a large surface high pressure residing over the Great Lakes region. Influence from the high will continue the dry weather trend into early next week as the gradient between the high and low induce gusty NW winds that are expected to continue through Saturday. Thereafter, the low will exit off into the North Atlantic, allowing the high to slowly slide southeast over the CWA which will allow the winds to diminish Sunday into Monday.
Temperatures will remain just below normal for this time of year through the weekend with cold overnight lows in the 20s and daytime highs in the 40s for most with low 30s across the mountains.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/.
Mainly dry weather is likely to continue Sunday through Wednesday with a notable warming trend Tuesday into Wednesday.
An upper-level trough that will be overhead on Sunday will move offshore by Monday afternoon as a region of surface high pressure builds locally. The surface high will slowly move offshore Tuesday into Wednesday allowing for return flow. This coupled with an upper- level ridge building over the Plains propagating eastward will allow for temperatures to soar into the 60s with 70 degrees possible in some of the warmer locales Tuesday into Wednesday.
It is possible we get through the entire long term period without any measurable precipitation. The next opportunity for precipitation arrives with a cold front Wednesday night into Thursday. Guidance varies regarding how much moisture if any will be associated with this feature.
AVIATION /20Z THURSDAY THROUGH TUESDAY/.
VFR conditions are expected to continue through the weekend with high pressure in control. Gusty NW winds around 20-30 kts will continue this afternoon and are likely to persist through Saturday. Winds will begin to diminish Saturday night as high pressure becomes more centralized over the region. VFR conditions are likely Sunday into early next week as high pressure builds nearby.
MARINE.
Gusty northwest winds are expected to continue over the waters through Saturday. As a result, SCA will likely need to be extended through Saturday night. Winds will begin to diminish thereafter as high pressure becomes more centralized over the region into early next week. Sub-SCA winds are expected Sunday into Monday.
FIRE WEATHER. Dry weather will persist through Saturday and the RH values will be low each day (20s and 30s today, teens and 20s Friday, and 20s to lower 30s Saturday). Gusty northwest winds are expected during this time as well, with frequent gusts around 20 to 30 mph for most areas. As fuels continue to dry out over the next few days, the meteorological conditions may enhance the threat for the spread of wildfires, especially Friday afternoon and Saturday afternoon (when fuels will be driest).
