Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
934 AM CDT SUN JUL 3 2016

.UPDATE...We're off to another humid and hazy start this morning
with dewpoints in the mid 70s across much of the CWA. The 12z KJAN
RAOB showed a somewhat drier airmass overhead, but blended satellite
total PW estimates and model data suggest a more moist ambient
airmass. Based on persistence, nudged high temps up in a few areas
just to maintain the same maximums reached yesterday. Given the
resulting instability, I expected isolated showers to break out
again. Considering that coverage was greater than anticipated
yesterday and little has changed in the overall setup, isolated
showers have been added to the forecast for today. Updated products
have already been sent. /DL/

&&

.AVIATION...VFR conditions are expected to prevail today. Isolated
showers may again be possible this afternoon but confidence in
affecting a TAF site is low and will be left out of the forecast for
now. Winds will be out of the south/southwest again today around 5-
10kts. /28/

&&

.DISCUSSION... /ISSUED AT 322 AM CDT SUN JUL 3 2016/
SHORT TERM...Ridging surface and aloft will shift a little farther
south Monday as a shortwave trough approaches our CWA. This
shortwave is expected to move over our northwest most zones during
peak heating and result in greater rain chances across the northern
half of our CWA Monday afternoon and Monday night. Afternoon
temperatures will be lower due to greater cloud cover and better
rain chances but, dew points look to hold to around 70F. Provided
early convection does not knock temperatures down prematurely, the
area along and west of the Mississippi river may see peak heat index
values at or above 105. The remainder of the CWA will see peak heat
index values of 101-104 again. Wl keep mention of the limited threat
of high heat for our west in our HWO. Models hint at the sea breeze
front spreading convection into our southern zones late afternoon
and early evening but rain chances will continue across the northern
half of the area Monday night as the shortwave moves across the
region. A few storms may produce strong gusty winds late Monday
afternoon and early evening primarily along the HWY 82 corridor.
/22/

LONG TERM...For Tuesday through Saturday Models generally differ
about about a weak short wave will slowly move through the CWA
before it dissipates. The Canadian and Euro model keeps the short
wave hanging around the region through early Wednesday....while the
GFS diminishes it by Wednesday. Otherwise flat upper ridging will
fluctuate some across the southern stream through the period.
Precipitable water will range from 1.5 to around 2 inches.
Instability combined with weak flow will bring some diurnal
convection across the region during Tuesday and Wednesday. With
generally weak flow around could be looking at slow moving convection
with some locally heavy rainfall for the period. With diurnal
convection may be looking at some gusty winds on Tuesday. As we push
farther into the week capping will increase across the region as the
upper ridge becomes a little stronger. This will limit convection
potential. So expecting generally dry conditions for Thursday through
Saturday.

As far as temps are concern we will continue above normal highs and
lows through the period. Expect highs to be mainly in the middle to
upper 90s for the long term. For Tuesday Heat indexes generally
along and west of the Ms River will be around 105. So will put a
limited heating potential graphic combined with Monday. Pooling of
low level moisture will bring lows mainly in the middle to upper 70s.
So we will be looking at some more heat potential with heat indexes
nearing 105 for the rest of the period...mainly in the west. The
GFS,Euro, and Ensembles show some potential for 2 meter 100 degree
temps during the period, which seems reasonable./17/
