000 FXUS61 KAKQ 271050 AFDAKQ Area Forecast Discussion National Weather Service Wakefield VA 650 AM EDT FRI MAY 27 2016 .SYNOPSIS... High pressure will remain centered well off the Mid Atlantic coast through today. Low pressure will slowly move northwest from well east of the Florida coast toward the South Carolina coast tonight through Sunday, then drifts northward along the coastal Carolinas Sunday night into Tuesday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... During today into tngt, upr rdg will bld alng the Mid Atlc cst with sfc hi pres remaining cntrd well off the Mid Atlc cst. The bldng upr rdg will help to push/keep aftn/eveng shower or tstm development alng and e of the mountains. So, will maintain just slgt chc (20%) POPS for nw counties. Highs today will be in the upr 80s/arnd 90 well inland/piedmont, while an increase in sse flow should keep it a tad cooler than Thu along the cst with Highs in the upr 70s to mid 80s. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/... Mostly clear to partly cloudy tngt with Lows in the lwr to mid 60s. For Sat, models remain in generally good agreement at keeping the deeper moisture associated with the low well off the SE cst to our south. They are even hinting at some large-scale subsidence, so have maintained POPS at only 20% and confined to ne NC in the aftn. Otherwise, partly or mostly sunny elsewhere with highs in the mid to upr 80s inland/piedmont areas, and in the upr 70s to lwr 80s along the cst. Deeper moisture finally pushes nwrd into the cwa later Sat night into Sun morning, with PWATS rising to 1.50 to 2.00" by Sun morning into the southern 1/2 of the CWA. Exact track of sfc low into the SE coast will determine sensible wx on Sun, but overall it looks like a warm and humid airmass will be in place and should be conducive to at least scattered showers and tstms. So, have raised POPS to 40-60% most areas. When track becomes more certain, will potentially need to raise POPS even more, although the setup does not look like a complete washout. Rather, expecting periods of potentially moderate to heavy rain alternating with a variably cloudy sky and rain-free conditions. Highs on Sun generally in the upr 70s to lwr 80s. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... The forecast for next week will be largely dependent on the evolution of the low pressure system expected to develop off the southeast U.S. coast within the next few days. 12Z suite of model guidance continues to support the development of this low by this weekend and NHC has high confidence of it developing into a tropical or sub-tropical low within next 5 days...and then drifting NW into South Carolina. Even if it does develop into a named storm, its impacts would most likely be minimal across our FA...with the exception of increased shower/thunderstorm chances and possible elevated seas/increased rip current risk Mon-Wed. For now, will continue to carry chc pops (30-50%) Mon-Tues...lowering a bit by next Wed/Thurs. Temperatures, tempered somewhat by clouds and possible convection, should be near normal through the period. Highs mainly in the upper 70s to low 80s. Remaining mild at night due to influx of higher dew point air. Lows in the 60s. && .AVIATION /12Z FRIDAY THROUGH TUESDAY/... Hi pres sfc-aloft off the mid atlc cst will dominate the wx during the 12Z TAF pd. FEW-SCT hi based cu once agn xpcd...w/ isold-sct tstms psbl primarily W of the TAF sites lt this aftn or eve. SSW wnds rmn aob 15 kt. No significant precipitation is expected through Saturday. Chcs for shras/tstms increase for Sun through Tue as lo pres tracks NW to the SC cst. && .MARINE... Hi pres sfc-aloft rmns off the mid atlc cst into the wknd. A bit of a surge in speeds (avgg 15 kt) fm S direction ongoing and will cont into the early mrng hrs then wane tda. S-SW winds 5-15 kt will continue through midday Sat before winds become more ESE at similar speeds into Sunday. Seas will remain 2-3 ft thru Sat...waves 1-2 ft. Contg to monitor psbl low pressure development off the southeast coast this weekend...which may bring increased seas/deteriorated conditions to the local waters Sun/Mon. For now...SE winds avg 10-15 kt Sun/Mon...seas may approach 5 ft...esp off VA/NE NC. && .CLIMATE... The monthly rainfall total to date for May at Richmond is 8.41".
