...New SHORT TERM, LONG TERM...

.SHORT TERM...
(This evening through Saturday Night)
Issued at 202 PM CDT Fri Apr 19 2024

A very diffuse frontal boundary continues to make very slow
progress across our southern zones attm with some very light rain
and/or drizzle continuing near the I-20 Corridor across N LA.
There will continue to be the possibility of an isolated
thunderstorm or two across our southern zones due to the
proximity of the boundary and diurnal heating but anything that 
forms should dissipate with the loss of daytime heating this 
evening. Then all eyes turn out west as an upper level disturbance
moves out of the Four Corners Region and into the Texas Hill 
Country during the day Saturday. Isentropic forcing in advance of 
the upper forcing in association with the upper trough itself will
result in increasing convective coverage near and north of the 
I-20 Corridor after midnight tonight. 

Likewise, ascent from the upper trough will only increase during
the day Saturday and especially Saturday Night with arrival of the
upper trough with widespread accumulating rainfall totals near 1-3
inches with isolated higher amounts. These kind of rainfall
amounts will likely be much more impactful to our area lakes,
rivers and bayous given how swollen they have been from previous
rainfall. Hourly Flash Flood Guidance Values across our region are
near 3 inches per hour and we should be nowhere near these kind of
rainfall rates for this event. Therefore, will not go out with a
Flood Watch with this package. Instead, we will issue a 
Hydrologic Outlook which highlights the likelihood of excessive 
heavy rainfall and its impacts on our waterways. Stayed close to
NBM MOS guidance temps throughout the short term portion of the
forecast.
