.SHORT TERM... /NEW/
/Now through Tuesday/

A complex of showers and thunderstorms continues to move through
North and Central Texas at this hour. Latest RAP objective
analysis indicates around 1500 J/kg of MLCAPE across our far
southeast counties, so a strong wind gust still can't be ruled out
with the strongest storms in that area. Elsewhere, a very moist
airmass remains in place and efficient rainfall production has
led to heavy rainfall and flash flooding across the region. As the
main shortwave responsible for this activity continues to move
east, most of the showers and thunderstorms should push out of our
area later tonight. At the surface, a weak area of low pressure is
centered just north of Wichita Falls with a cold front draped
across central Oklahoma into West Texas. This front will slide
southward overnight and could be a source for additional
convective development, however, instability is waning in the wake
of this afternoon's complex and chances appear to be diminishing.
We've lowered PoPs overnight across the region, although we'll
keep some 30-40% PoPs along the front through the overnight hours.
Any additional rainfall will result in continued flooding issues.

Latest guidance continues to suggest that the front will push
through our area early tomorrow and despite weak large scale
ascent, we'll remain generally precipitation free. While it should
be noticeably less active, we'll keep some low rain/storm chances
along the front across our southern counties. Rain chances should
increase again late tomorrow night as another surge of moisture
spreads northward.

.LONG TERM... /Issued 303 PM CDT Mon May 31 2021/
/Tuesday night through next Monday/

The main story of the extended portion of the forecast continues to
be the daily precipitation chances across North and Central TX
through the next weekend. The combination of the rain and clouds
will keep the temperatures below average with highs in the upper 70s
to mid 80s and lows generally in the mid/upper 60s to near 70
degrees.

The highest precipitation chances will slowly shift to East and
Central TX Tuesday night into Wednesday as the weak cold front
settle over this area. For the rest of us, expect spotty showers and
storms with a coverage between 20-30% throughout the day on
Wednesday. There's a chance that our region remains precipitation-
free during the day due to some subsidence in the wake of the front.

A couple of disturbances will travel across our region late week and
into the weekend, as the upper level trough continues its way to
the east and another mid-level low pressure settle over the
southwest CONUS and northern Mexico. This will keep PoPs in the
forecast through his weekend, with best chances across Central TX.
At this time, flooding rainfall will be the main concerns throughout
the week with heavy rain possible each day. However, we can't
rule out some brief gusty winds with some of the stronger storms.
Flash flooding issues will likely increase each across those
locations that see multiple rounds of heavy rain throughout the
next several days.

.AVIATION... /NEW/
/00Z TAFs/

VFR prevails across the Metroplex at this hour in the wake of
heavier rainfall, and the 00Z Fort Worth sounding shows quite a
bit of dry air below 10,000 ft. Given all of the rainfall and
diminishing winds, we should see reductions in cig/vis during the
overnight hours. We'll continue with IFR cigs after midnight and
assess this through the late evening as vis restrictions may be
the bigger issue toward morning. Wind fields were northerly
earlier but have recovered in the wake of convection and are
primarily easterly now. We should see a gradual shift to northerly
winds as the front moves through late tonight.

Cigs/vis will improve during the day Tuesday with VFR prevailing
by afternoon.
