NWS Forecaster Discussion

Aviation... 
VFR through the period. Drier air working in from the northeast 
overnight should help to limit fog threat across northern sites. 
May see some shallow ground fog across our southwestern sites 
briefly around sunrise but no significant impacts expected. 38

Previous discussion... /issued 341 PM CDT Wednesday Oct 22 2014/ 


Discussion... 
the near term Continental U.S. Synoptic pattern will be of a midwestern 
surface ridge filling in along the back side of a New England 
Nor'easter with the amplification of a Desert Southwest middle- 
upper level ridge. This will maintain the lower level north to 
east flow pattern needed to keep mean lower to middle 50 dew 
points in place through early Saturday. The very dry air mass 
now residing over the southeastern states will assert a bit of an 
influence upon eastern Texas...if nothing more than to fortify 
precedent dry conditions. Afternoon mix out will have surface 
humidities falling to under 50% through Friday evening. Pacific northwest 
energy riding up and over amplified western upper ridging will 
dive down and deepen a late week middle-Atlantic trough while the 
ridge begins to flatten out going through the weekend. This chain 
of events will aid in veering easterlies around to onshore by the 
cob Sunday. The eastern expansion of the upper ridge equates to 
near none rain chances and makes this set of products primarily 
temperature/moisture forecasts. 


The region may get clipped by a the western extension of the 
aforementioned eastern Continental U.S. Trough passage Friday. This...in 
tandem with upper ridging enveloping Texas...will veer middle-level 
winds around to more of a south or west component. Flattened middle- 
upper ridging/northern Gulf surface high...with weak Rocky Mountain 
troughing...may veer middle-level winds enough southwest to warm 
subsequent days by a few degrees. 10-500 mb thickness values are 
modeled to increase by an additional 50 or 60 meters through next 
week. Partly cloudy conditions from middle-high clouds will regulate 
any significant warmth...but have increased weekend T numbers by 
a couple of degrees to side with the low Standard dev men numbers. 
Extended model inconsistencies between the GFS and European model (ecmwf) on the 
existence of a passing trough/frontal passage have just kept slight or 
lower probability of precipitation in grids. Recent trends have favored the faster more 
shallower trough passages (gfs) so will remain cautious on when to 
bring rain back into the discussion. 31 


Marine... 
dew point 9 located near the Yucatan Peninsula will move slowly east through 
Saturday. The gradient between this feature and high pressure over 
the Great Lakes will gradually weaken overnight as the depression 
moves east. Will maintain the scec for the offshore waters through 
06z for mainly elevated seas...but sea heights will also begin to 
dampen out with time. Tide levels are expected to remain within a 
half foot of normal. 


A northeast flow will more or less stay in place through Saturday 
before winds veer to the south and increase on Monday. Once again... 
speeds will approach scec criteria on Monday. Another weak cool 
front will approach the coast late Tuesday or early Wednesday. 43
