Area Forecast Discussion

941 PM CDT Sun Apr 2 2017

As the convection continues to move off to the ENE across LA and
points beyond, the cold front is starting to make its way slowly
into SE TX this evening. Looking very N-S aligned so far, we are
still expecting this boundary to move through the CWA overnight.
Grids appear to have things covered, so no major changes we made
with the update. 41


.PREV DISCUSSION... /ISSUED 404 PM CDT Sun Apr 2 2017/

Today`s event is coming to a close...with the only action left on
the radar that of thunderstorms racing up ahead of an early
outflow boundary that propagated from a ragged line of storms just
northwest of the city. Although not a complete bust as there have
been reports of trees downed and flooded roadways across the
northern CWA (4 to 5 inches of storm total precipitation from
central Grimes County northeast into Houston County)...the bulk of
the population (i.e., Houston metro) did not experience any
severe thunderstorm activity. With such a ripe downstream
environment conducive for the formation of tornadic cells that are
now impacting SHV and LCH`s area...the greater Houston area did
dodge a bullet. The main `why`s` to this may be pinned on poor
upper air/jet dynamics...the upper low`s slow movement into the
Big Bend region this afternoon really placed the best diffulence
west of us. The gust front generated by the QLCS over the western
CWA early this afternoon blew through the city and virtually
outraced the upstream cells...shutting the door on future
development as rich and warm inflow was cut off by lower level
cool moist downdraft air. Activity flaring up over Jackson County
may need to be monitored but all high rez solutions as not doing
anything with its future evolution.

The Pacific front is entering central Texas this hour and should
be veering winds west through the late evening into the early
Monday morning hours. Spectral models (for as much as they can be
trusted) maintain far eastern forecast area early evening QPF just
ahead of the front. Prefer to go with the guidance that suggests
all that will occur with the fropa will be clearing skies and
lowering temperatures/dew points. Today was pretty much it
concerning precipitation so hopefully you picked some up rain today
without the added storm wind feature. Dry slotting behind the
exiting upper low into the Midwestern CONUS tomorrow morning will
clear skies and allow temperatures to fall into the upper 50s to
near 60 F. A mostly sunny Monday as afternoon temperatures warm
into the middle 80s under a southwest breeze...relatively lower
dew points in the 50s will keep RHs comfortable. Tuesday will be a
partially cloudy day as the region falls between the Bermuda high
and lowering Rocky lee pressures. A brisk south breeze Tuesday
with near 60 F minimum temperatures...warming into the middle to
possible upper 80s by the early afternoon. There may some maximum
temperature records that will be threatened Tuesday afternoon as
many Tmax records are in the middle to upper 80s. An upper trough
moving out of the Rockies will push a surface cold front through
eastern TX overnight Wednesday morning. Primarily a dry fropa with
slight chances for pre-dawn Wednesday showers ahead or along the
boundary across our southern tier counties. Uneventful weather
through late week under mostly clear air mass
will regulate warmth to the middle to upper 70 maxTs / upper 40
to lower 50 minTs. 31
