NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
423 am CDT Thursday Oct 2 2014 


Short term... 
active weather pattern is in the process of commencing. Upper level 
trough is currently racing eastward across the rockie mountains. 
Meanwhile...copious moisture has been surging into the area with middle 
to upper 70 dewpoints now in place. Scattered showers and 
thunderstorms will begin to break out across the County Warning Area today...likely 
middle morning and Onward. Expecting spacial coverage of them to be 
quite limited without much upper level forcing in place just yet. 
The main show comes in tonight at surface pressures begin to fall and 
instability increases from middle level cooling. Although there/S still 
some timing differences between GFS and European model (ecmwf)...with the latter 
being the slower of the two by 3-6 hours. The actual will probably 
be something in between with the most intense storms passing across 
the County Warning Area from early to late morning as the cold front moves in. Model 
soundings indicate ample instability but lack appreciable wind/shear 
intensity for severe development. It appears that 500mb winds barely 
reach 40 knots. Thats not to say there won't be strong storms with 
gusts into the 40 miles per hour range and there will likely be plenty of 
lightning moving through. Just not looking like much severe. 


Rain chances will then quickly taper off on the back side Friday 
afternoon and evening...with most precipitation exiting the coastal waters 
by midnight. 


Long term... 
should be rain free for the rest of the weekend as the trough swings 
through and high pressure builds in. Post frontal cooler air will 
drop temperatures substantially Saturday and Saturday night with the coldest 
temperatures we've seen since last Spring headed our way. The latest 
forecast will show highs struggling to reach middle 70s on Sat and temperatures 
falling into the upper 45s that that night. In general...the GFS was 
slightly warmer than this and European model (ecmwf)/met were quite a few degrees 
cooler. The official forecast is a blend of the two. 


Temperatures will rebound fairly quickly as the air mass begins to 
modify even by Sunday...but especially early next week. Expect highs 
back into the middle 80s by probably Tuesday. Another shot of rain 
possible Tuesday as a secondary trough rotates through the 
southeast. While another brief cooling period is possible after this 
boundary moves through according to the GFS...will side with GFS/S 
more shallow trough as previous forecast depicts. 


Meffer 
&& 


Aviation... 
MVFR category ceilings have developed and expanded over 
areas from near kl38-kbtr-khdc-kmcb...and these clouds should 
expand across other taf airports overnight with tempo IFR ceilings 
possible. Conditions will vary between VFR and MVFR through the 
day and evening on Thursday. Scattered rain showers/isolated thunderstorms and rain are 
expected in the morning with a bit more thunderstorms and rain expected in the 
afternoon. Will insert tempo thunderstorms and rain for all taf sites this afternoon 
and prevailing rain showers after 06z Friday for btr and mcb. 18 


&& 


Marine... 
light to moderate southeast to south flow will prevail 
this morning through this evening. This flow will increase through 
the day as the pressure gradient increases between a departing 
high over the eastern Seaboard and developing low in the plains. 


A strong cold front will push across the coastal waters late Friday 
afternoon into Friday evening. 1000 to 700mb thickness layers will 
hover around 3055m before the frontal passage. Strong cold air 
advection after the front will allow layers to drop to 2990m by 
Saturday 12z and GFS holds the this layer through through Sunday 
morning...similar to Euro. 


GFS and Euro have the surface high over the lower Mississippi Valley 
Saturday night. GFS is still slightly quicker with the frontal 
passage on Friday and the surface high tracking east of the area 
early Sunday. With high building the over the region by Saturday 
night coupled the sharp trough axis shifting east...the strongest 
northwest winds throughout the column will shift to the eastern 
Seaboard. Will carry Small Craft Advisory condition Friday night 
through Saturday morning...then dropoff wind speeds out the 
northeast and east late Saturday night/Sunday morning. Southeast 
flow will develop over the coastal waters by Sunday afternoon and 
persist through early Tuesday of next week. 18
