Update... 
some additional information...an National Weather Service storm survey is enroute to 
the Grimes County area to assess damage. We will update with 
information as we receive it from the assessment. 


Peak winds measured last night 
Conroe ASOS 62 miles per hour at 435 am 
8se of Navasota 55 miles per hour at 412 am 
Huntsville ASOS 54 miles per hour at 452 am

Update... 
the area has been stabilized for the morning hours. Have pared 
back the rain chances this morning...but...this afternoon is a 
very different story. A squall line that raced through the region 
knocking down trees is well into la with subsidence/drying across 
the northern County Warning Area. Outflow boundary (with a small cluster of 
storms) in the nearshore waters with surface dewpoints down to 
63-67 over southeast Texas. Low level convergence currently stretches from 
the nearshore waters up through Matagorda Bay to Giddings to just 
west of Fort Worth. Water vapor/upper air clearly shows a drying trend 
aloft with strong SW flow of 50+ knots at 500mb and 80+ knots at 
300mb. As we heat up and the upper low near Wichita Falls 
continues to trek east this should place southeast Texas in a favorable 
region for severe weather with synoptic scale lift...ll 
convergence and a rapidly destabilizing atmosphere. Sb cape 
values soar to 3500-4500 j/kg over the north with the 
aforementioned shear aloft and low levels only somewhat sheared 
highlight the potential for hail/damaging winds/isolated 
tornadoes...though probably a lower threat for tornadoes but that 
is a lot of cape if we can reach the 80 degree mark. The storms 
should swing eastward through the evening hours ending the threat 
of severe weather. Storm Prediction Center has kept the area in a slight risk. Heavy 
rain threat possible but should be more isolated in nature. Cold 
front should arrive in the Houston area after 2 am with moderate 
cold advection. Breezy conditions expected Tuesday.

Aviation... 
confidence in the forecast is low due to the variability in model 
solutions. The high resolution hrrr model agreed with the global 
models in moving the current convection east of the area while 
possibly developing more showers and thunderstorms this afternoon 
as the upper low in nm moves into the Southern Plains. 


For this morning...do expect VFR conditions from kiah northward. 
The MVFR to IFR conditions from khou to the coast should improve 
by the middle morning period. Will add the mention of showers or 
thunderstorms this afternoon into the early evening. 


Although guidance was forecasting low ceilings...raw model output 
suggested best chances will be more toward the coast. At least 
MVFR conditions are possible from khou to the coast ahead of the 
cold front. The front is expected to at least move through kcll 
and kuts by around 08z...and should move through kcxo and kiah by 
12z.
