Personal note - after 33 years in government and 23 years at LWX I`m calling it a day. It`s been a great honor to serve my country. Thank you. And a very wild end to the ride it`s been on this overnight shift. I suppose there are records on it, but I doubt there have been too many Oct 24s that have featured 70 dewpoints at 2 am. This is more like what youd see in late July. But over the past two hours some of this moisture has been wrung out as the cold front is now crossing the I-95 corridor. The band of precipitation may be slow to clear the Bay and will hold onto at least PoPs until late afternoon. This will be the final day of well above average temperatures with highs in the 70s.

&& .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... Upper trough axis crosses the area Wed (GFS) or Wed night (ECMWF) with temps staying in the 60s during the day and 40s at night. Any precip would be confined to the upslope areas. && .LONG TERM /THURSDAY THROUGH MONDAY/... Troughing will remain entrenched over the eastern CONUS through the period as ridging persists out west and over the North Atlantic. This will lead to near normal temperatures late this week into the weekend. A spoke of energy will rotate around an upper low stationed just southwest of James Bay likely bringing another period of unsettled weather at some point next weekend, but timing/placement details remain fuzzy this far out. && .AVIATION /09Z TUESDAY THROUGH SATURDAY/... IFR/MVFR ceilings at the major sites early this morning will see improvement as the morning progresses. Then VFR tonight. Mainly VFR expected late in the week with light flow. && .MARINE... We are seeing Gale level gusts on the Bay. This will be in effect for the widest portion of the MD section of the Bay until 3 pm, further north until 8 am. Then SCA everywhere for the remainder of the day. Light flow with high pressure over the waters Thu-Fri. && .TIDES/COASTAL FLOODING... Waters are running above normal on southerly flow. Advisories are in effect along the western shore of the Bay thorugh midday. && .LWX WATCHES/WARNINGS/ADVISORIES...
