NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
406 PM CDT Monday Apr 20 2015 


Synopsis... 
latest surface analysis showed a cold front from Ohio to Florida 
Panhandle to northwest Gulf. Surface dewpoint readings were in the 
40s across most of west Louisiana and northern two-thirds of 
Mississippi. Ridge of high pressure was located from southwest 
Kansas to north central Texas. Upper air analysis showed a large 
cyclonic over Minnesota with west to northwest flow over plains 
and Mississippi Valley. Isotach analysis showed the southern 
stream from Baja California California to north central Gulf. 


&& 


Short term... 
dry air and high pressure will settle in tonight through Tuesday 
night. These features along to near calm winds will allow good 
radiational cooling tonight and Tuesday evening. With dewpoints 
bottoming out near 50f across northwest forecast area...cant rule 
a 49f at mcb and north of btr Tuesday morning. The main trough 
will shift east leaving a westerly flow over the forecast area and 
lower Mississippi Valley early Wednesday. Surf high will slide 
Georgia and return flow will bring in 60s dewpoint by 18z 
Wednesday. Ridge over The Rockies will slide east and create a 
west northwest flow over Southern Plains and lower Mississippi 
Valley Wednesday afternoon and Wednesday night. In embedded 
disturbance will dive down on the front side of the ridge and 
trigger convection over Southern Plains Wednesday afternoon. This 
convection may hold together with the active jet stream and 
instability in play. Isolated strong storms may clip the north and 
east areas of forecast areas...possibly parts of east central 
Louisiana north of Lake Pontchartrain...extreme south central 
Mississippi and coastal Mississippi late Wednesday afternoon and 
Wednesday evening. Albeit is slight...hail and damaging winds are 
the main threats. Cooler 500 mb temperatures around -16c will remain north 
and hail threat will diminish farther south into our forecast 
area. 


With no real push at the surface...low level instability 
will remain in play on Thursday and a chance of convection will 
remain across the area. Upper level ridge will continue to slide 
east and allow daytime surf temperatures to warm Thursday through 
Saturday. Ridge will slide east as a short wave move east across 
the Central Plains Friday through Saturday. Dry air entrainment 
south of the wave will tighten the moisture axis across the area 
Saturday and Saturday night...thus maintaining a chance of 
convection. As the wave pushes east...dry air will press the 
moisture axis south Sunday and provide a slight break on Sunday. 
Another wave will dive south over the plains bringing a shot of 
cool air next week. 18 


&& 


Aviation... 
VFR conditions expected to prevail through the period with generally 
only high clouds. Winds expected to shift from northwest this 
afternoon to easterly by Tuesday morning with speeds generally 10 
knots or less. Main exceptions will be those terminals on the 
immediate South Shore of Lake Pontchartrain. 95/dm 




&& 


Marine... 
northwest winds of 10 to 15 knots will increase to exercise 
caution range this evening and overnight with winds up to 15 to 20 
knots and wave heights getting up to around 3-5 feet over the 
open waters. Winds will quickly return to an onshore early 
Wednesday morning as high pressure passes to the east of the 
area. Winds will remain around 10 knots during the middle of the 
week...but could ramp up to about 15 knots at the end of the week 
as another front approaches. Wave heights at that time could get 
up to 4-5 feet over the open waters. 18
