.DISCUSSION...

Issued at 214 AM MDT Thu Jun 27 2024

Currently, the skies are overcast with showers and a few
thunderstorms across parts of the CWA. The temperatures are mild,
and the winds are light to breezy. Some of these showers will
continue through the early morning hours while dissipating. For
today, there will be slight break in active weather conditions by
around mid morning. However, with heating around noon, and an
abundance of moisture and weakness within a ridge of high pressure
that appear to flatten out, showers and thunderstorms will
develop across the mountains at first and then across the lowland
areas along outflow boundaries. The winds will be light to breezy;
however, in and around thunderstorms the winds can be windy. The
main concerns with these storms will be heavy rainfall that could
lead to flash flooding. Also, as mentioned before, the winds
could strong from strong downdrafts. This ridge of high pressure
will be centered across the South Plains, which will allow for the
temperatures especially in the lowlands to still be above the
normal, but they will not be as warm as they were yesterday
afternoon. Storm coverage today will not be as they were
yesterday. The coverage today will be a little less than they were
yesterday. These storms will continue at least through the
midnight hours. As with yesterday`s storms, some of the storms
could possibly linger through early morning hours on Friday. The
air will be humid and with cloud coverage; thus, the low
temperatures on Friday morning will be above the normal. By
Friday, the ridge definitely flattens out and centering across
eastern Texas. There will be a few storms developing in the
mountains; however, Friday should be a less active day. With less
storm coverage, the high temperatures on Friday will begin to
increase a couple of degrees from what they will be today despite
the center of the ride across eastern Texas. The temperature for
EL Paso will be at or very near the Heat Advisory criteria on
Friday.

By Saturday, the center of this ridge will be across the the
Lower Mississippi Valley. With this set up in place, showers and
thunderstorms will be possible in the mountains and across areas
west of the Rio Grande. The temperatures on Saturday will be the
warmest of the weekend with triple digit heat for much of the
lowland areas. By the latter half of the weekend, the ridge
amplifies across the Plains while it centers across eastern
Oklahoma and northeastern Texas. As it does, it will enhances
moisture across the area and with diurnal heating showers and
thunderstorms will be likely across much of the area. However,
the the bulk of the storm coverage will be to areas west of the
Rio Grande. This pattern will continue through the much of next
week as monsoonal moisture continue to move in and be focused
over Arizona and New Mexico bringing daily chances for active
weather conditions. The ridge will maneuver a bit from across the
South Plains to the Southeast. Also, toward the end of next week
another ridge of high pressure from the Pacific west will build in
across the western Continental US, which will not decrease our
chances for precipitation as of yet. With lots of active weather
next week, the lowland temperatures in the lowlands will be in
the mid to upper 90s and lower one hundreds.

.FIRE WEATHER...
Issued at 214 AM MDT Thu Jun 27 2024

Showers and thunderstorms will continue today especially in the
afternoon and the evening. The main impacts from these storms
will be heavy rainfall that could lead to flash flooding and gusty
erratic winds. Flooding will definitely be a concern across burn
scar areas. The 20ft winds will be light to breezy and the
temperatures above the normal. Showers and thunderstorms will
continue at least through midnight. Tonight recovery will be good
to excellent. For Friday, some moisture will be in place; however,
the chances for showers and thunderstorms will decrease. The best
chance for showers and thunderstorms will be in the mountains and
in the Bootheel. The 20ft winds will continue to be light to
breezy except in and around thunderstorms with the temperatures
above the average. Thursday overnight recovery will be fair to
good. For the rest of the period, active weather conditions will
persist with breezy winds and at and above normal temperatures.
With that being said, there will be no fire weather concerns
throughout the period.

The min RHs today will be between 19 and 25% in the lowlands and
between 30 and 45% in the mountains. The min RHs on Friday will
decrease 3 to 6% across the entire zones. The ventilation rates
will be poor to very good today then poor to excellent on Friday.
