10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kakq 221937 afdakq area forecast discussion national weather service wakefield va 337 pm edt Tue oct 22 2019 Synopsis A cold front will cross the region this evening. High pressure returns Wednesday and Thursday. Another cold front crosses the area over the upcoming weekend, bringing another chance of rain. Near term until 6 am Wednesday morning As of 255 pm edt Tuesday... st from earlier has generally lifted to bkn-ovc CIGS 1200-2500 ft inland and on the ERN shore (except well wnw of ric over the piedmont where CIGS remain blo 1000 ft)... Sct-bkn higher CIGS in se va-ne nc. Warmer more humid air has made some progress N into the fa this afternoon... But substantial clearing has been reluctant to occur. Shras beginning to spread over more of wrn central portions now and that will continue far to the ene this evening ahead of an approaching cold front. A narrow shallow line of shras crossing the area may contain brief heavy ra and gusty winds. Svr threat is limited at best. The shras in the line now moving through wcentral va only have tops to about 12000 ft... Not expecting much more dramatic development far E this evening as near term hi res guidance shows CAPE quite limited. Cold front through the I 95 corridor by 00z 23 then off the coast by 04-06z 23. Gusty sse winds ERN portions will last until the frontal passage. Winds become wnw overnight resulting in clearing. Lows from 40-45f wnw to the m50s at the immediate coast. Short term 6 am Wednesday morning through Friday As of 225 pm edt Tuesday... drier (not too much or any cooler) for wed-thu. Sfc hi pres builds in from the w-sw post-frontal and becomes centered over the local area Wed night-thu. Highs in the m60s to around 70f wed... Then on Wednesday, and in the u60s-l70s thu. Lows in the u30s wnw to around 50f at the immediate coast Wed night. Models continuing to struggle W wx for the end of the week (fri). GFS nam quicker W return of moisture from the wsw while the (00z 22) ECMWF was slower. Went W a blend of the guidance... Leaning slower W clouds and any pcpn during fri. Partly sunny becoming mostly cloudy (late) W highs mainly in the m-u60s... L70s se. Long term Friday night through Tuesday As of 330 pm edt Tuesday... the GFS and ECMWF still differ greatly in the long term. GFS keeps an open trough moving across the southern plain into the southeast us. While, the ECMWF cuts off a upper low across west texas and northern mexico with a shortwave moving east across the great lakes and northeast us. Therefore, the GFS was disregarded for the long term. Using mostly the ecmwf, chance of precip will be near zero for Saturday after the passage of a weak cold front. Sfc high pressure will move in for Saturday with seasonable temperatures (highs in the 60s and lows in the 40s inland to 50 near the coast). Pops were increased for Sunday (30-40%) as the upper low over texas moves ne into the western great lakes then into ontario. This will likely bring showers back into the region as warm southwest flow begins. The ECMWF then forms an upper ridge along the carolina and ga coasts, with a sfc high pressure system off the carolina coast for the beginning of next week. This will keep temperatures mild for the first half of the week, with highs in the low 70s and lows in the 50s. A slight chance of showers will remain in the forecast for the |
beginning of next week as well. Aviation 20z Tuesday through Sunday As of 125 pm edt Tuesday... bkn MVFR-vfr CIGS and sse winds occasionally gusty to 20-25 kt (esp at the coast) continuing into this evening ahead of an approaching cold front. An area of shras will be tracking across the fa... Mainly from 20z 22 to 03z 23. A narrow line of shras may contain brief gusty winds heavy ra. A short period of possible ifr CIGS right after the cold front exits pcpn ends this evening then wnw winds bring drying overnight. High pressure builds into the area for the midweek period.VFR conditions wed-fri as sfc hi pres moves across the region. Flight restrictions (from lowered CIGS vsbys and additional ra) are possible by Fri night-sat as lo pres tracks into the region from the sw. Marine As of 330 pm edt Tuesday... afternoon surface analysis shows deep low pressure over the u.P. Of michigan with a cold front extending southward to the big bend of florida. Another (much weaker) area of low pressure has formed along the front across the va nc piedmont. Southeasterly winds have increased to 10-15 knots with gusts to 20 knots ahead of the low front. Waves are 1-2 ft and seas are running 3-5 ft. Southeasterly flow will continue until the front crosses the waters this evening. A narrow line of showers is noted along the front this afternoon and hi-res guidance continues to show this feature into this evening. Winds will be locally enhanced along this line and could gust 25-30 knots as it passes. Otherwise, winds turn NW 15-20 knots behind the front before slowly decreasing toward daybreak. Waves will decrease to 1-2 ft but seas will stay near 4-6 ft through Wednesday mid-morning. Current SCA headlines for the bay extend until 7am Wednesday morning with the offshore zones in effect until 10am. High pressure builds in for the remainder of the week.&& Tides coastal flooding As of 400 am edt Tuesday... coastal flood statements and advisories are now in effect for areas adjacent to the upper bay for the upcoming high tide. Anomalies have continued to rise early this morning across the upper bay, coming in around a foot to a foot and a half. This will allow for locations along the tidal potomac and upper bay to approach minor flood thresholds later this morning. S to se winds increasing ahead of a cold front will allow for anomalies to remain high into the evening tidal cycle, thus additional coastal flood headlines will likely be needed.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
