NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wakefield Virginia 
1124 am EDT Friday Sep 4 2015 


Synopsis... 
a backdoor cold front will move south across the area later today 
and tonight. Strong high pressure across the northern states will 
slowly build south to off the middle Atlantic coast Saturday through 
Sunday. Low pressure develops off the southeastern coast late in 
the weekend. 


&& 


Near term /until 6 PM this evening/... 
very warm/humid conds at this time. Made only minor adjustments to forecast. 
Continue to favor convection (highest probability of precipitation ~ 30%) along-west of I 95. 
No severe weather expected...but could see gusty winds and lclly heavy downpours 
given precipitable waters at or above 1.5 inches. Hi temperatures from the u80s at the CST to l90s 
inland...W/ heat indices reaching the M/u90s most places. 


&& 


Short term /6 PM this evening through Sunday/... 
front pushes south across the region this evening before weakening 
into a elongated trough off the Carolina coast ivof the Gulf Stream 
wall. Thus...kept thunder chances across the Piedmont through 00z. Airmass 
becomes more stable by late evening and overnight...however the combo of 
lingering moisture at different levels and the increasing NE wind flow leads 
to the need to keep at least slght chance probability of precipitation going through the night 
under pt to mostly cloudy skies. Becoming breezy at the coast as well with 
gusts up to 25 miles per hour. Highest probability of precipitation late tonight shifts toward the 
coast due to the moist flow off the ocean. Lows u60s-l70s. 


What once looked like a dry and cooler weekend now appears to be 
rthr unsettled due to little movement in synoptic features. Add to that 
a dvlpng area of low prs off the southeastern coast results in periods of 
low level cloudiness and a rthr gusty NE wind along the coast (25-30 
mph). Latest data also suggests weak middle level disturbances tracking 
across the region resulting in the need to keep 20-40 pop across the 
southern half of the forecast area Sat. Driest across the north closer to the center 
of the high. Cooler given the above scenario with highs u70s-l80s. 


Precipitation chances (20-40%) continue to shift towards the coast Sat night as the 
high prs extends SW across the mts keeping thw western half of the forecast area 
dry. Lows Sat night m60s-l70s. 


Moisture from the coastal trough and the persistent onshore flow will likely 
lead to addntl showers (20-40 pop) moving onshore and making as far west 
as the i95 corridor Sunday before shifting towards the coast once 
again Sunday night. Highs Sunday u70s-l80s. 


&& 


Long term /Sunday night through Thursday/... 
long term period starts off Sun night and Monday with surface low pressure 
spinning off the Carolina CST with hi pressure north and west of the forecast area. 
Resultant onshore flow will lead to temperatures only making it into the 
middle 80s Monday under a prtly-mostly sky. With the moist onshore flow 
did hold onto some slight chance-chance probability of precipitation over much of the forecast area 
sun ngt/Mon. Kept thunder out due to a lack of instability. The 
surface low weakens and starts sliding east Tuesday allowing for drier conds 
and temperatures rebounding into the middle/upper 80s under a prtly cloudy 
sky. Dry weather continues midweek with temperatures further increasing as southerly 
flow develops ahead of the next cold front...with hi temperatures in the 
upper 80s to near 90 Wednesday and Thursday. The front will cross the area 
sometime late Thursday or Friday. 


&& 


Aviation /16z Friday through Tuesday/... 
areas of MVFR fog/haze expected early this morning...with a chance 
for brief IFR visibilities at kphf and kecg between 09z-12z. Otw...VFR 
conditions to continue today outside of isolated to widely scattered afternoon 
convection...mainly along and west of Interstate 95. 


Outlook...periods of sub VFR conditions will occur in areas of 
showers and in early morning fog/stratus Saturday through Monday 
with onshore flow. In addition...gusty winds are expected along 
the coast on Saturday. 


&& 


Marine... 
a weak trough of low pressure over the waters this morning is 
producing light north-northwest winds. NE flow develops all waters by late 
morning/afternoon as a backdoor cold front drops south towards the 
region and high pressure overspreads the NE states. Winds will 
slowly increase through the day over all waters...reaching 10-15 knots 
everywhere by early evening and 15-20 knots over the northern ocean 
zones. Winds increase a bit more Friday night so that sca's will 
be necessary for the Ocean/Bay/lower James River...with waves on 
the Bay building to 3-4 feet and seas reaching 4-6 feet (highest 
north). The start time of the Small Craft Advisory for the southern coastal waters 
(south of cape charles) was pushed back about 12 hours (til 7am sat) 
as it will take the longest for Small Craft Advisory conditions to be realized 
there. All sca's will then run through the day Sat. May also need 
to include the Currituck Sound during the day Sat but not 
confident enough at this time due to short duration of highest winds. 
Conditions improve Sat night for most of the Bay and lower James 
so that the sca's can end. Still expecting waves to remain around 
4ft at the mouth of the Bay into Sunday morning...with seas 
lingering around 5 feet. Sub-Small Craft Advisory conditions appear likely to start 
next week. 


In addition...the onshore flow and high nearshore waves will enhance 
the rip current threat for the Holiday weekend.
