Short term
ongoing convection affecting areas mainly west of i-35 and north
of i-20 should continue into the early evening hours, with
activity being focused primarily along multiple mesoscale
boundaries. The most well defined outflow boundary continues to
push southwest across the CWA this afternoon, and the best rain
chances will likely shift to areas west of i-35 but south of i-20
early this evening. Isolated storms may linger into the later
evening hours across the southwest, but just about all showers and
storms will dissipate by midnight.

Rain-cooled air is providing a nice cool-down along the red river
counties this afternoon. With the synoptic scale front remaining
to the north of the area, a gradual return to southeast winds can
be expected at all locations this evening and temperatures should
rebound to near normal values tonight. Conditions should still be
slightly cooler compared to the past few nights, with lows in the
mid 70s across most of the region, and upper 70s in the urban


Long term
Saturday onward
a somewhat active period will continue into the extended portion
of the forecast, as the upper ridge continues its gradual
breakdown. For Saturday, this will mean additional convective
chances, particularly through the afternoon and evening hours, as
a subtle shortwave drifts along the northern periphery of the
ridge axis. In addition, the presence of any residual boundaries
from activity today tonight could aid localized ascent. With
fairly weak flow through the column, the environment will be
rather typical for summertime pulse convection with limited
effective shear but moderate instability. Any robust convection
during peak heating will support a threat for downburst winds.

Northwesterly flow aloft will increase a bit on Sunday as the
upper ridge becomes displaced farther to the west. This will be in
wake of the aforementioned disturbance progged to move through on
Saturday, so some weak subsidence may prevail, keeping much of
the forecast area dry. Will continue some low storm chances near
and east of i-35 within the better moisture, but convective
coverage will likely be lower than on Saturday. In addition, some
higher temperatures and heat index values should exist during the
afternoon, with dewpoints struggling to mix out of the 70s.

The peak in heat over the next several days may occur on Monday
as the low-level thermal ridge axis expands into the forecast area
ahead of a developing surface low and upstream frontal zone.

Widespread temperatures around 100-105 with higher heat index
values will likely necessitate a heat advisory. Convective chances
appear low on Monday without any well-defined lifting mechanisms
in place. However, the frontal zone will continue to sag southward
heading into Tuesday, likely stalling in the vicinity of the red
river. Fairly widespread convection should accompany this
boundary, which may reinforce its southward push via consolidated
outflows. Previously, guidance had indicated this boundary and
possibly a convective complex moving into our area as early as
Tuesday, but latest guidance has delayed its arrival slightly into
Tuesday night or Wednesday. There will continue to be some
uncertainty on this potential for a few more days, but this setup
does warrant some higher rain chances for parts of north texas.

There could be a slightly higher threat for strong severe storms
with this system as well (particularly wind), although this may be
conditional on storms' time of arrival and whether they have
access to surface-based instability.

The frontal zone should continue to linger across the area
Wednesday and Thursday, leading to some additional convective
chances. The ridge will remain centered to our west through the
remainder of the week, and the presence of the front along with
increased cloud cover should hold temperatures below the century
mark. In fact, parts of north texas may experience some below
normal temperatures through the second half of the week.

18z tafs
outflow from morning convection along the red river is surging
south and should arrive at dfw and surrounding airports within the
hour. The metroplex tafs will therefore begin with north winds and
vcts. Though storms may remain scattered, the current feeling is
that coverage will be enough to warrant a tempo group for thunder
mid to late afternoon. Convection will wane this evening while
winds eventually turn back to the southeast. Due to a persistent
weakness in the ridge, diurnal convection will likely re-develop
Saturday afternoon, and vcts has been included in the extended dfw
taf beginning tomorrow afternoon.

For kact, vcsh has been added, as it looks like mesoscale
boundaries may reach parts of central texas by late afternoon.

Held off including thunder due to the expectation that stronger
subsidence will keep development to a minimum in the central texas

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
