What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Discussion
Through Wednesday afternoon:
globs of heavy rain and thunderstorms over the northwestern gulf of
mexico and portions of coastal SE tx and SW la have fed lots of mid
to higher level clouds downstream over the lower ms valley today,
holding temperatures below 90 degrees in many locations (except for
eastern ms). This morning the thickest mid layer clouds produced
light rain showers over mainly the arklamiss delta but most of this
light rain diminished several hours ago. However, the slow thinning
of the cloud shield has allowed for enough destabilization
juxtaposed with modest low level southeasterly wind shear to drive
more significant shower and thunderstorm activity coming into
southwestern zones. This activity should not have access to quite as
much shear as this time yesterday and thus should fortunately not be
capable of as much gusty wind as was the case with some storms
yesterday. Anticipating most of the convection to drive
north northwestward through western zones during the evening and
largely diminish overnight, although a stray and light late night
shower cannot be again ruled out over the delta. Any fog tonight
should be very patchy and mostly confined to the southeastern ms
pine belt.

Tomorrow, the upper level low responsible for today's widespread
clouds and scattered afternoon thunderstorms in southwestern zones
should be drifting further to our southwest. This should set our
region up for a little less mid to upper level cloud cover and more
opportunity to heat up and destabilize. In fact, heat indices could
manage to hit, or at least approach, 100 degrees along and south of
the natchez trace corridor. A solid shortwave aloft in association
with inflecting westerlies to our north and northwest will begin its
approach to our region by late in the afternoon. The influence of
this feature should start to tilt gulf moisture advection more to
the north (as opposed to the current SE to NW orientation) and allow
for a better overall late afternoon coverage of showers and
thunderstorms than we are seeing this afternoon. Bb
Wednesday night through Monday night:
models remain in good agreement that a closed low will drop over
the central plains Wednesday night into Thursday becoming centered
over the mid mississippi river valley Friday before lifting
northeast and weakening Friday night into Saturday. This will
serve to increase rain chances areawide Thursday and Friday. There
may be some concern for heavy rainfall and perhaps a marginal risk
for severe storms late this week with precipitable water > 2
inches and unseasonably high levels of low-mid level flow. Models
are in better agreement this morning with the associated cold
front that looks to stall between highway 82 and interstate 20
Friday night before lifting back north of our CWA Saturday. Rain
chances will decrease Saturday as the low departs the region and
as broad ridging aloft builds back across the gulf coast states.

This will lead to a warming trend as well through Monday. Will
still be left with a moist airmass through Monday and as sites top
out closer to the mid 90s. Peak heat indices look to exceed 100f
Sunday afternoon and approach 105f Monday afternoon. 22 ec

Aviation
18z TAF discussion:
skies will remain mostly cloudy through the day along and west of
the i-55 corridor, although ceilings are mainly above 5 kft and
vfr conditions are anticipated. In these areas some scattered to
isolated showers and thunderstorms are possible late this
afternoon into this evening with low potential for direct impact
bringing gusty winds and temporary sub-vfr conditions. Some light
showers may persist through the night around glh, otherwise the
potential for sub-vfr conditions is not very high in any one spot,
but certainly cannot be totally ruled out come sunrise.

Thunderstorm activity may be a little more prevalent tomorrow
afternoon, especially along and west of i-55. Until then winds
will be light and tending toward variable at times. Bb
