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 161105 afdakq area forecast discussion national weather service wakefield va 705 am edt Wed oct 16 2019 Synopsis Periods of rain Wednesday ahead of a strong cold front. Gusty winds are expected behind the front Wednesday night into Thursday. High pressure builds in for the end of the week resulting in cool and dry weather. Near term until 8 am this morning As of 600 am edt Wednesday... rain started moving into the southwest portions of the cwa around 9z. Adjusted the near term pops a little further east. Rainfall amounts through 12z will be light across the southwest, likely a trace to about a tenth of an inch. Surface obs and satellite confirm much of the region is now overcast as mid and high clouds have spread over the area. Some patchy fog can be found in areas that saw a little bit more clearing earlier this morning, mainly richmond and areas northwest, as well as portions of the md eastern shore. Short term 8 am this morning through Friday As of 345 am edt Wednesday... some much needed rain will spread across the entire region today. The forecast challenge today will be in the amount of rain that falls across the area. A cold front associated with a low pressure centered over the great lakes will approach from the west today. This system will interact with another low expected to develop near or just off our coast this morning. Latest hi-res models show that rain should start to overspread the region from SW to NE beginning after 09z. Moderate to heavy rain is expected at times from late morning through the afternoon, before tapering off near 00z tonight. Region wide QPF amounts will be in the 0.5-1.0 inch range, with localized higher amounts. SPC has our region outlooked for general thunder today. Highest chances for that will be across the eastern half of the forecast area as instability increases modestly during the afternoon and early evening hours. Mostly cloudy skies and periods of rain will keep temps on the cooler side today, with mid to upper 60s over the western half of the CWA and lower 70s near the coast. After the cold front crosses the area tonight, wnw winds will become gusty as drier cooler air begins to filter into the region. Wind gusts by late Thursday morning will be 25-35 mph and that will continue through much of the day before relaxing to 10-20 mph by late Thursday into early Friday. Low temps will drop to the low to mid 40s for most on Thursday and Friday with near 50 degrees close to the coast. Wouldn't be surprised to see some upper 30s across the far nw. High temps will be cool and pleasant reaching the low to mid 60s both days. Long term Friday night through Tuesday As of 230 pm edt Tuesday... sfc hi pres moves out off the coast Fri night through sat resulting in dry near seasonable wx. Return flow behind the high once its off the coast Sun through Mon will bring an increase in moisture (and pops) from the SW ahead of lo pres tracking through the midwest - initially inland late Sun sun night... Then all areas mon. A cold front is expected to cross the region tue w additional ra chcs. Lows Fri night 40-45f inland to the l50s at the (immediate) coast. Highs Sat in the u60s-l70s. Lows Sat night in the u40s inland to the l-m50s at the coast. Highs Sun in the l-m70s. Lows sun night in the m-u50s... Except l60s at the coast. Highs mon from the l70s N to the u70s far se. Highs Tue in the u60s NW to the u70s. Aviation 11z Wednesday through Sunday As of 700 am edt Wednesday... rain will overspread the region this morning with the heaviest rain expected late morning through the afternoon hours before tapering off this evening. Expect periods of MVFR ifr ceilings and visbys, especially during times of moderate to heavy rain. There is a slight chance of thunder across the eastern portion of the forecast area today, but chances are too low to mention in the tafs. All locations should return toVFR after 00z tonight. Winds will be S SW ahead of the front turning to the W NW during the afternoon. Winds will |
become quite gusty behind the front, with gusts of 15-25kts and perhaps 30kts at ksby. Strong gusts will continue through Thursday before diminishing overnight into Friday morning.VFR conditions are expected Thursday through Saturday. On Sunday a storm system originating in the gulf is forecast to ride up the carolina coast. Depending on the track of this system, some showers could affect the region which may result in periods of subVFR conditions. Marine As of 330 am edt Wednesday... sub-sca conditions prevail early this morning with a SE wind around 10 kt on avg and seas of 2-3 ft, bay waves 1-2 ft. Conditions will slowly worsen later today and then really deteriorate in the wake of a strong cold frontal passage this evening. Only real change to the forecast was to convert the gale watch for the coastal waters N of CAPE charles to a gale warning and to upgrade the northern bay zone (smith pt to windmill pt) to a gale warning. These areas are expected to see a prolonged period of gusts to at least 35-40 kt this evening into early Thu am (potentially 40-45kt coastal waters N of parramore island). Elsewhere, strong scas (due to winds) are expected starting this evening through Thu night. Do anticipate a brief period of higher gusts this evening W the frontal passage (about 2 hrs worth of occasional gusts to 35-40 kt). May need to issue a short fused smw to cover this but felt that a gale warning would be too long for short term event. Seas will build to 5-7 ft n and 4-6 ft s, while waves in the bay build to 3-5 ft, and 2-3 ft waves in the rivers. The current forecast has winds remaining aoa SCA thresholds for bay and coast through ~12z fri. Sub-sca conditions return by late fri, as high pressure settles over the waters. Tides coastal flooding As of 330 am edt Wednesday... seeing some slowly increasing tidal anomalies into the bay and will let current coastal flood statement continue over dorchester co md for the next few hrs. Will then likely be issuing another coastal flood statement and or advisory across much of the upper bay for the upcoming high tide cycle this aftn due to a continued increase in tidal departures as the sse winds increase and with cbofs forecast for a dominant flood tide through the aftn helping trap water into the bay. Then, in the wake of the cold front tonight, strong wnw flow will lead to a strong ebb tide for ~24 hrs through thu. This will lead to significant drops in water levels across the bay. Does not appear to be enough to lead to low water advisories given the initial elevated water levels. Akq watches warnings advisories Md...

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. |
