10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 231433 afdakq area forecast discussion national weather service wakefield va 933 am est Wed jan 23 2019 Synopsis A series of low pressure systems will track northeast along the mountains today and Thursday. The associated warm front lifts north of the region later today with the trailing cold front crossing the area Thursday. High pressure builds in again for the weekend. Near term until 6 pm this evening As of 615 am est Wednesday... latest msas has the arctic high well off the mid atlantic coast with low pressure over il. Meanwhile, a warm front snaked it way from off the sern coast west to low pres over ark. Models take the first low NE into the great lakes region with the warm front slowly lifting north from the deep south. Latest data suggests the front doesn't get this far north until closer to sunset. Ahead of it, a return and moistening upslope flow will continue to allow clouds to thicken up as the day progresses. Any rain chcs remain over the piedmont today (generally W of i95) where low chc pops will be maintained, dry elsewhere under cldy to mstly cldy skies. Temps slow to rise this morn, but increasing southerly winds this aftrn will allow temps to rise thru the 40s and 50s with the highs not achieved until late aftrn. Short term 6 pm this evening through Friday night As of 300 am est Wednesday... the warm front lifts north of the local area this evening leaving the fa in the warm sector overnight. Meanwhile, moisture from the second area of low pressure overspreads the region starting late in the evening over the west then over the rest of the area after 06z. Chc to low end likely pops this eve ramp up to high end likely and categorical after midnight. Some mdt to lclly hvy rainfall enters the piedmont late. Much warmer with nearly steady temps thru the night from the mid 40s NW to mid 50s se. The low tracks NE across the region Thu morning with the trailing cold front crossing the area thru the day, pushing offshore by 00z fri. Data shows a decent slug of SRN stream moisture combined with strong lift btwn 12z-18z just ahead of the cold front. Some convective elements noted for a band of lclly heavy downpours. Thus, added some r+ for a few hr prd. Pcpn quickly tapers off to some light rain or shwrs Thu aftrn west to east as the front pushes all the deep moisture towards the coast. Mild with highs 55-60 north to 60-65 south. Can't rule out some elevated thunder along the sern beaches in the aftrn, but left thunder out of the fcst thinking it remains offshore closer to the gulf stream wall. QPF arnd one inch. Clearing and colder thurs nite as high pressure builds in from the nw. Lows mid 20s NW to mid 30s se. Back to below normal temps fri and Fri nite. Plenty of sunshine fri. Highs upr 30s NW to mid 40s se. Lows Fri nite upr teens NW to upr 20s se. Long term Saturday through Tuesday As of 310 pm est Tuesday... the extended looks fairly quiet at least for our region as the main storm systems stay north or west of the area... Or well offshore. High pressure over the area Saturday gradually shifts ne through Sunday with the ridge axis staying in place across the area. A weak upper disturbance moves well north of the area later Sunday which may allow for some light precipitation Sunday night, but given the lack of moisture will keep just a slight chance of rain (or snow across the nw). Warm advection again develops Monday into Tuesday as upper heights build ahead of another great lakes low pressure system. The associated cold front is expected to approach the area on Tuesday with chance of rain across the west and north. Highs over the weekend will be seasonably cool with temps in the 40s Saturday and mid 40s-lower 50s Sunday-Tuesday. Aviation 15z Wednesday through Sunday As of 615 am est Wednesday... high pres now offshore with low pres west of the mts. A warm frnt lifts north of the local area after 18z. High and mid level moisture continues to overspread the area today so will keep a sct-bkn sc deck btwn 3-4k ft. South winds become gusty this afternoon (15-20 kts) and continue thru the night (20-30 kts). Wind shear btwn 40-50 kts at 2k ft due to a strong low level jet. Rain oversreads the area west to east after 06z |
along with lowering cigs. Kept CIGS just above 1k ft for now but do expect to see some ifr CIGS and vsbys in rain and fog overspreading the area thurs morning. Outlook... low pressure and trailing cold front will affect the area Thu morn with ifr restrictions both in rain and fog. High pres briefly returns thurs night... Before another cold front sfc trough crosses the area on fri (conditions look to remainVFR Thu night into the weekend). Marine As of 930 am est Wednesday... seasonally strong surface high pressure continues to move offshore early this morning with winds across the marine area becoming southerly at 5-15 knots. Waves are 1-2 feet in the bay with 2-4 foot seas offshore. A digging upper trough across the central portion of the country is allowing surface low pressure to deepen across the mississippi valley. Increasingly steep pressure gradient between the departing high and approaching low will allow winds to increase in magnitude through the course of the day and especially into the evening and overnight hours tonight. Southerly winds in the bay increase to 15- 20 knots this afternoon with 20-25 knot southerly winds by this evening offshore. Small craft advisories will begin for the bay and northern offshore zones shortly after noon and all the rivers, currituck sound, and remaining offshore zones following suit a few hours later. Winds and seas will increase further overnight into Thursday as a secondary area of low pressure forms along the trailing cold front. Winds in the bay will run 20-25 with gusts to 30 knots by Thursday morning while winds offshore increase to 25-30 with gusts to 35 knots. A few gusts could exceed 35 knots during this period, especially across the northern offshore zones. Opted not to issue a gale watch with this package due to the relatively brief window for gale conditions and the less than climatologically favored southerly wind direction, however, will continue to watch this period closely in subsequent forecasts. Seas will build as winds increase Thursday morning with 8-12 foot seas possible across the northern offshore zones, slightly lower to the south where 5-9 foot seas are expected. Will have to monitor for the potential for a high surf advisory on Thursday from roughly cape charles light northward. Winds will become northwesterly behind the surface cold front late Thursday afternoon. Cold advection behind the front appears rather anemic with northwest winds 15-20 knots in its wake, decreasing further Thursday evening. Seas will be slow to subside Thursday and scas for offshore zones will likely need to be extended into Friday to cover this threat. High pressure builds into the region on Friday with tranquil marine conditions in store through the upcoming weekend. Equipment As of 300 am est Wednesday... the kakq radar is down due to a pedestal slip ring assembly failure. Due to the time to procure ship the needed parts, and the repair time, the radar will remain down through at least Friday. Akq watches warnings advisories Md... None. Nc... None. Va... None. Marine... Small craft advisory from 4 pm this afternoon to 10 am est Thursday for anz635>638. Small craft advisory from 1 pm this afternoon to 1 pm est Thursday for anz630>632-634.
