NWS Forecaster Discussion
536 fxus61 klwx 250143 aaa afdlwx Area forecast discussion...updated National Weather Service Baltimore Maryland/Washington District of Columbia 943 PM EDT Thursday Jul 24 2008 Synopsis... high pressure will build across the middle Atlantic through the end of the work week. A cold front will cross the area on Sunday. High pressure return over the region next week. && Near term /through Friday/... Center of high pressure over western WV will move eastward overnight and be centered over the eastern ww Panhandle by sunrise. Clear skies and cool tonight west of I-95. Lowered temperatures in the west due to low dewpoints running in the upper 30s. Expect lows to bottom out near 40 in the usual cold spots in the west with middle 50s across northern Virginia to low 60s along and east of I-95. Middle 60s in city centers. && Short term / Friday through 6 am Friday/... high pressure will reside over the middle Atlantic on Friday...providing plentiful sunshine with only a scant few cumulus. Dry air will warm quickly...with high temperatures easily rising into the upper 80s. && Long term /Friday through Thursday/... there remains a great deal of uncertainty with the medium range. Inconsistencies remain when it comes to the strength and timing of the upper trough. The GFS is stronger and more progressive with a cold front moving through on Sunday. The NAM has energy remaining well to the north and little if anything happening over the area this weekend. Went with HPC guidance as a starting point..but more optimistic through most of the long term given uncertainty. A pre frontal trough will develop Saturday afternoon and evening. Combined with some instability...expect showers and thunderstorms during the afternoon and into the overnight. Main frontal boundary will move through on Sunday...triggering more showers and thunderstorms. The front will be off the coast by late Sunday evening. Due to inconsistencies in timing...will need to keep chance probability of precipitation in Saturday afternoon through late Sunday night. There will probably be a dry period sometime late Saturday night into Sunday morning...but confidence not high enough at this time. GFS brings a couple waves across the southeast and middle Atlantic through the remainder of the forecast period with an upper low and trough stuck over the eastern US. The next cold front across the area will be late next week. && Aviation /02z Friday through Tuesday/... VFR cumulus will dissipate this evening. Dry air will squelch fog development overnight as high pressure remains in control through Friday. Showers and thunderstorms are expected Saturday afternoon through Sunday night as a cold front moves through the region. High pressure will then return briefly early next week. && Marine... light and variable winds overnight and Friday Showers and thunderstorms are expected Saturday afternoon through Sunday night as a cold front moves through the region. Southerly winds ahead of the front may approach Small Craft Advisory criteria late Saturday. High pressure will then return briefly early next week. && Lwx watches/warnings/advisories... District of Columbia...none. Maryland...none. Virginia...none. WV...none. Marine...none. && $$ Update...Rosa products...peloquin/sar
