(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 192019 afdakq area forecast discussion national weather service wakefield va 419 pm edt Sat oct 19 2019 Synopsis Post tropical cyclone nestor will track northeast across the carolinas tonight and Sunday morning, then push off the delmarva coast Sunday afternoon. A strong cold front will cross the area Tuesday. Near term through Sunday As of 345 pm edt Saturday... latest msas has high pressure moving off the mid atlantic coast while the center of post tropical cyclone nestor was located across sern ga. Models generally agree in moving the low NE across ERN sc this eve then into the coastal plain of nc by 12z sun. The low then tracks NE ivof the albemarle sound late Sun morning, exiting off the coast and into the va capes Sun aftrn. This track will bring a widespread rainfall across the entire area along with gusty winds along the coast. While the track in the models is similiar, the QPF forecast differs on where the axis of heaviest pcpn falls. It will all depend on where the best f-gen forcing bands set up. GFS sref has the heaviest rainfall across the south east while the NAM canadian shift the heaviest bands into the piedmont. Overall, looking at at 1-3 inch rainfall across the fa (highest se) but low confidence for any flood watch ATTM given a quick moving system. Look for clouds to lower thicken this eve with rain overspreading the area south to north after midnite, lclly hvy rain psbl across the south late. Pops arnd 100% except likely to low end cat pops across the lwr md ERN shore after midnite. Lows in the 50s except for some upr 40s ivof sby and near 60 ivof ecg. This systm will result in a rather large temp gradient Sunday with a fairly strong insitu-wedge setup across the piedmont. Temps go nowhere across the nwrn zones (low-mid 50s) while readings jump into the lwr 70s across the SE on the warm side of the triple point low. Given the track of the remnant tropical low, added slght chc thunder sern most va zones and NE nc zones that border the albemarle sound. Potential for a waterspout across NE nc as well. Otw, pops at 100% for mdt to lclly hvy rainfall thru 18z with the axis of heavier rain shifting east towards the coast in the aftrn, becoming lighter and actually tapering off across the west late as the systm pulls offshore. Short term Sunday night through Tuesday As of 345 pm edt Saturday... any lingering rain will end along the coast Sun eve followed by pt cldy skies overnite. Gusty winds continue along the coast. Lows mid 40s NW to mid 50s se. We dry out Monday as a weak area of high pressure builds in. Expect pt sunny skies along with diminishing winds. Highs 65-70. Dry to start off Mon night but moisture increases ahead of an apprchg cold front to the west after 06z. Will keep low chc pops mainly west of the i95 corridor after midnite for now. Lows 55-60. The cold front crosses the area tues. With the gom opened up, ample moisture is progged to ride north along the bndry tues. This results in yet anther round of moisture in the form of shwrs. Will carry likely-high chc pops with the rain tapering off late across the west as the front pushes offshore. Mild with highs upr 60s nw-mid 70s se. Long term Tuesday night through Saturday As of 345 pm edt Saturday... cold front will be moving off the coast by Tuesday night pushing out most of the rain showers. High pressure will move in behind the front an will remain overhead for the end of the week. Conditions will remain dry with seasonable temperatures. High temperatures will be in the upper 60s to near 70 and lows will be the 40s inland and low 50s near the coast. Next chance of rain will come with a front that may approach the area by late on Friday. Aviation 20z Saturday through Thursday As of 115 pm edt Saturday... vfr conditions along with light winds to start off the forecast period as high pressure moves off the coast. The remnant low of tc nestor will move NE along the carolina coast Sun morn then off the DELMARVA coast Sun aftrn. Expect lowering thickeningVFR cigs this eve with widespread rain and MVFR CIGS overspreading the area south to north after midnite tonite and continuing thru |
the end of this forecast period. CIGS will likely lwr to ifr Sunday over most of the area along with rain of varying intensities. Se wind becomes NE and gusty to btwn 20-30 kts across va md while a gusty south wind continues at ecg until the low passes by to the ne. Outlook... lwr CIGS rain and gusty winds (strongest along the coast) with nestor will continue Sunday evening with slowly improving conditions late Sunday night. Monday will be dry as high pressure briefly builds in ahead of a cold front that is expected to cross the area Tuesday. Scattered showers are expected ahead of the front which may result in brief periods of subVFR conditions. Marine As of 345 pm edt Saturday... afternoon surface analysis shows high pressure over the local area with the post-tropical extratropical remnant center of nestor along the florida panhandle. Most of the rain and stronger winds are located across georgia, south carolina, and the lower fl peninsula... Well to the east of the low center. Winds are generally light and variable with the high overhead but are becoming increasingly SE this afternoon into the evening. Waves in the bay are around 1 ft and seas are 2 ft offshore. 12z models have come into better agreement regarding the track and strength of the storm formerly known as nestor. Model consensus has slowed the approach of the low by about 6 hours vs the 19.00z suite. Conditions will deteriorate after midnight with SE winds increasing into the 20-25 knot range in the southern bay and 20-30 across the southern offshore waters by mid morning. The low is forecast to exit the coast in the early afternoon with winds quickly turning to the north over the bay and northeast north over the northern coastal waters. Winds should briefly diminish over southern waters and veer around to the nnw and increase again behind the departing low. There is the potential of a brief period of gale force gusts across the bay coastal waters Sun evening (driven by CAA on the back side of the low). Seas build to 6-9 ft by late Sunday waves to ~4 ft (4-5 ft at the lower bay mouth of the bay). Have upgraded all gale watch headlines to gale warnings and made minor adjustments to hazard start times to accommodate the slower onset of stronger winds. All previous scas remain in place for the rivers and northern bay. Northerly winds quickly diminish below SCA thresholds all zones Monday morning (although seas may remain elevated through at least mon night). Winds remain below SCA thresholds through much of tue before another cold front crosses the waters Tue evening-later tue night. Tides coastal flooding As of 420 pm edt Saturday... no coastal flooding is expected through tonight. However, water levels are expected to rise as the remnant low of t.C. Nestor tracks from SE nc to offshore of the va nc coast Sun aftn and night.
