AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1001 AM EST Tue Jan 21 2020

SYNOPSIS. Canadian high pressure builds into the Mid-Atlantic from the northwest today, and then spreads across the area through midweek. High pressure slides offshore later in the week as low pressure approaches from the west.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1000 AM EST Tuesday .

Adjusted grids late this morning per current trends. Main change was to bump up the cloud coverage across the nrn OB as clouds from the ocean low continue to rotate in. Other change was to increase winds a bit based on the gustiness (15-25 kts) being reported this morning. This again due to the pres gradient around the ocean low. Otw, sunny and cold. Highs 35-40, wind chills in the 20s.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/. As of 345 AM EST Tuesday .

High pressure gradually builds across the region Tuesday night into Wednesday as low pressure pushes ewd well off the Southeast coast. Clear and cold tonight with lows in the upper teens/low 20s for much of the area, and upper 20s/around 30F for coastal SE VA/NE NC. Mostly sunny Wednesday with temperatures moderating toward seasonal averages. Forecast highs range from the low to mid 40s.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 345 AM EST Tuesday .

The end of the work week will be dry and mild, with high pressure at the sfc and aloft over the region. At the same time, an upper-level trough will be digging south into the Midwest/Central US. The trough will become a closed low and cut off from the main upper-level flow and slowly migrate east. As the closed low pressure aloft moves towards the east coast, it will likely stay northwest of the southern Mid-Atlantic. However, a sfc low will likely develop east of the Appalachian Mountains and track from SW to NE across VA/MD. This will bring an area of rain through the region Friday night into Saturday morning. As the sfc low moves north of the area, rain will exit the area for Saturday evening/night. However, the low pressure system aloft will still be nearby and may give areas across central and northeastern VA and central Delmarva a few rain showers Saturday afternoon/evening. A NW, downslope, low will begin late Saturday/Sunday and dry the area out.

Throughout the Long Term period, temperatures will be near average to above average. Friday's high temperatures will be in the upper 40s W (perhaps mid 40s NW due to in situ CAD wedge) to mid/upper 50s SE after morning lows in the upper 20s to mid 30s Friday morning. As rain moves into the area, temperatures and dew points will increase, temperatures on Saturday morning will range from the upper 40s across northeast NC and southeast VA to the upper 30s across central VA and MD Eastern Shore. Temperatures during the day on Saturday will be dependent on the exact track of the sfc low pressure. Highs may reach 60F across Hampton Roads and northeast NC, while a CAD wedge may persist in the central VA Piedmont, keeping temperatures in the 40s. Temperatures for Sunday and Monday will be close to average for late January, highs in the mid-upper 40s and lows in the 20s/30s.

AVIATION /15Z TUESDAY THROUGH SATURDAY/. As of 645 AM EST Tuesday .

Strong high pressure over the Mississippi Valley is building into the Mid-Atlantic region as of 12z. Meanwhile, broad low pressure is located well offshore. Therefore, the pressure gradient is maintaining a N wind of 5-10kt inland, and 10-15kt along the coast with occasional gusts to 20kt (and up to 25kt at ORF). Some bands of SC ~4-6kft are pushing onshore near ECG. The wind will remain N today ~10kt RIC/SBY/PHF, and 12-15kt at ORF/ECG, with gusts to 20-25kt through mid-aftn. The wind will relax tonight and become very light from the N inland, and NNE 5-10kt toward the coast.

High pressure builds into the region Wednesday into Thursday as low pressure pushes ewd well off the Southeast coast. High pressure slides offshore Friday. Low pressure and an associated cold front impact the region Friday night into Saturday bring a chc of rain and degraded flight conditions.

MARINE. As of 345 AM EST Tuesday .

Early this morning, strong high pressure is centered over Missouri. This is resulting in a northerly flow over the area waters. Winds are 15-20 kts over the bay, southern coastal waters, and Currituck Sound. Winds over the northern coastal waters are 5-15 kts. Waves in the bay are 3-4 ft, and seas are 5-6 ft. SCA for the northern coastal waters and southern James river should be allowed to expire later this morning, however SCA's will remain for the central and southern coastal waters, Currituck Sound, and the bay. Low pressure is expected to develop well off the SE coast on Tuesday, while the previously mentioned high pressure will drift eastward towards the ohio valley. This will result in a N/NE wind direction over the local waters. Wind speeds 15-20 kts with 20-25 kts over the southern coastal waters and Currituck sound. Waves in the bay are likely to remain 3-4 ft. Seas will be 2-4 ft in the northern coastal waters and 5-7 ft in the southern coastal waters.

High pressure builds over the region Wednesday and Thursday. Low pressure and an associated cold front will impact the area waters late Friday into Saturday.

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.
