National Weather Service Huntsville Alabama
947 am CDT Friday Aug 1 2014
minor adjustments to weather for this morning.
regional radar indicates reflectivity returns in northwestern Alabama/northestern MS/southern
Tennessee. Thus far, no reports of measurable rainfall have been received at
automated weather stations in the area. I suspect at least sprinkles may
be falling, much like on Thursday. Water vapor imagery shows a
shortwave now tracking through central/northern Alabama with a good deal of dry
middle to high level air flowing in behind on nwrly flow. In low levels,
the airmass continues to moisten due to easterly flow. Precipitable water profiles
have climbed above 1.5 inches at bmx, but remain around 1.0 inch at
ohx to the north. Satellite and observation indicate a low stratus deck tied
to the better moisture transport in the boundary layer over our southeastern
counties and into eastern Alabama and Georgia. We will continue to carry a low
pop of rain showers/thunderstorms and rain this afternoon, although the departing shortwave may
lessen this chance as we go through the afternoon hours.

for 12z tafs...
VFR conds are expected at both terminals through the taf period. Showers
in the vicinity of the terminals today will dissipate around sunset
this evening. As the upper disturbance responsible for this activity
moves across the region beginning early tomorrow, another round of
showers/storms is anticipated. For now, will introduce vicinity
thunder tomorrow after 11z, but the brunt of the activity should hold
off until middle-morning Saturday, lingering through the afternoon hours.
