NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
741 PM CDT Tuesday Aug 4 2015 


..sounding discussion... 


The elevated dry layer present last evening is eroding as more 
moisture enters the column. The precipitable water value has 
jumped up by 0.6 inches from last evening to 2.1 inches this 
evening. As has been discussed in the forecast discussions the 
last few days...the return of moisture has allowed for more 
thunderstorms to form. Most of the thunderstorms today have been 
confined to south of the tidal lakes...where storms still persist 
this evening. These storms are moving slowly with a mean storm 
motion of 1 knot /yep...1 knot/ from 096. Winds throughout the 
atmosphere are less than 20 knots and variable in direction. 
Stronger winds near the surface are the result of an outflow 
boundary that moved over the office about 20 minutes before 
balloon release. 


00z balloon info: a successful flight this evening that ascended 
to a height of 21.3 miles above the ground bursting over Lake 
Pontchartrain 28 miles downrange of the office. The balloon's 
ascent lasted 95 minutes.

Previous discussion... /issued 341 PM CDT Tuesday Aug 4 2015/ 


Discussion... 
above normal temperatures expected to persist through the period 
with significantly warmer than normal temperatures possible over 
the weekend. 


Rain chances increase for Wednesday and Thursday as a shortwave 
trough dives southeastward around the periphery of the upper level 
ridge. Am carrying generally 30 to 40 percent probability of precipitation each day. The 
convective activity should keep the afternoons from getting too 
uncomfortably hot. Afternoon highs forecast in the low to middle 
90s...with maximum heat index values topping out just over 100. 


The real heat turns on beginning Friday as the upper high 
strengthens over northern Texas and Oklahoma...spreading eastward 
toward the local area. Expect highs to rise into the upper 90s and 
though it/S not currently in the forecast...could even see one or 
two places flirt with the three digit mark over the weekend. With 
a lack of convection to help cool things down...am also carrying 
heat index values peaking in the 108 to 110 degree range for many 
places...so another round of heat advisories may be necessary over 
the weekend. 


If model guidance can be believed...hopefully the oppressive heat 
will only last a few days as both the GFS and Euro are indicating 
the East Coast trough will sharpen during the first part of next 
week. As this happens...both models force a weak frontal boundary 
through the local area and usher in some drier air. Of course 
this comes with the usual caveat of being 7 plus days out and 
somewhat in the realm of Dart throwing. 


Aviation... 
not as much definition to mesoscale vorticity that was mentioned in 
previous discussion. Convection is rather isolated at this time and 
only occasionally producing lightning. So will only carry vcsh for 
the southshore terminals through around sunset. Can not rule out 
a brief MVFR ceiling during the late afternoon hours...but should 
be predominantly VFR. 


Expect VFR conditions will continue through much of Wednesday 
morning. Anticipate that 00z taf package will need to address some 
sort of mention of convection at all terminals in the 05/18z-06/00z 
window. 


Marine... 
Bermuda upper ridge gradually building westward with low level flow 
generally becoming southwesterly to west. We should start seeing the 
usual evening enhancement of wind speeds over chandeleur and Breton 
sounds and much of the eastern coastal waters. Winds could get up 
around 15 knots at times during the evening hours and exercise 
caution headlines cannot be ruled out starting about Thursday 
afternoon. Pattern likely to persist through at least the weekend. 


Decision support... 
dss code....blue. 
Deployed...none. 
Activation...none. 
Activities...river flood warnings on Mississippi River from Red 
River Landing to Donaldsonville. 


Decision support services (dss) code legend 
green = no weather impacts that require action 
blue = long fused watch/warning/advisory in effect or high 
visibility event 
yellow = heightened impacts with short fused watch/warning/advisory 
issuances; radar support 
Orange = high impacts - slight to moderate risk severe; nearby 
tropical events; hazmat or other large episodes 
red = full engagement for moderate risk severe and/or direct 
tropical threats; events of National significance
