The flow of the Frio River in Concan has dropped to zero cubic feet per second, according to the U.S. Geological Survey. At Garner State Park visitors cannot enjoy tubing due to the low levels and can swim only in certain parts of the river.
Garner State Park issued a park alert, urging park visitors to conserve water and to bring their own drinking water. The use of showers may be limited.
Extremely low river flows can let the water stagnate, causing algae blooms or harmful bacteria, so people recreating should be careful in such areas of the Frio River. The water will be tested by the Texas Commission on Environmental Quality next week and the findings made available to the public.

Prior Lake is lower than normal due to hot, dry weather. There is more beach than usual, and several parts of the lake are dangerously low, so boaters should avoid those spots.
It’s dry in the Twin Cities, and the grass is brown.

On the afternoon of June 23, 2022, a wildfire (River Fire) started approximately 6 miles Northeast from the City of Burkburnett. The fire was located in heavy brush, mesquite, and sandy terrain.The Burkburnett Fire Department (BFD) were on a small 4-acre fire on the Southeast side of town, as they were toned out to a larger fire on the opposite side of the city, to what it became known as the River Fire. BFD requested assistance from surrounding fire departments to include State resources from Texas A&M Forest Service (TAMFS), and Federal resources from Sheppard Air Force Base. TAMFS resources arrived and worked with BFD under a unified command. The increasing temperatures are becoming more frequent, the vegetation is drying up making it more susceptible to igniting. As the small 4-acre fire (Lonely Fire), was controlled, BFD were toned out to a third fire (Green Fire), 5 miles Southwest of town, it was controlled at 7.5 acres. Please be mindful of the high temperatures, low...

Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1135 AM CDT Fri Jun 24 2022
Valid 241700Z - 251200Z
Added an Isolated Dry Thunderstorm delineation across the
south-central Sierra. Morning forecast soundings and CAM guidance
support the threat for isolated thunderstorm development.
No changes were made to the ongoing IsoDryT area in northwest
Arizona and southern Utah. Numerous storms are expected across
north-central Arizona where fuels are also dry, but PWAT will be
slightly higher across this region. Therefore, no scattered DryT
area is needed.
..Bentley.. 06/24/2022
.PREV DISCUSSION... /ISSUED 0139 AM CDT Fri Jun 24 2022/
...Synopsis...
Large-scale upper ridging will prevail across much of the central
and southern CONUS as a weak mid-level trough traverses the interior
West today. Some dry and breezy conditions may develop across the
southern High Plains in association with surface lee troughing, but
fuel receptiveness is expected to remain modest enough to temper
more widespread wildfire growth. Monsoonal mid-level moisture will
continue to meander across the Southwest into the Four Corners and
foster isolated to potentially scattered thunderstorm development
during the afternoon. While storm motion will be slow, forecast
soundings depict inverted-v profiles, where fuels are highly
receptive to fire spread. Isolated dry thunderstorm highlights were
added where the greatest chance of drier thunderstorms will overlap
the most receptive fuels.

Valid 241630Z - 251200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PORTIONS
OF NORTH DAKOTA...SOUTH DAKOTA...AND NORTHERN MINNESOTA...
...SUMMARY...
Severe thunderstorms with the potential for widespread damaging wind
gusts, very large hail, and a couple of tornadoes are expected from
the eastern Dakotas into northwestern Minnesota this afternoon into
tonight.
...ND/SD/MN...
Morning water vapor imagery shows a broad upper trough across the
northern Rockies today, with an embedded shortwave trough currently
along the MT/WY border. This feature will track into the northern
Plains later today, with large scale forcing for ascent
overspreading parts of the Dakotas. Strong heating across
eastern/central ND and convergence along a surface boundary will
lead to afternoon thunderstorm development from south-central into
northeast ND. Other storms will form by late afternoon to the north
of the boundary across western/central ND as the upper trough
approaches. Forecast soundings suggest strong instability (MLCAPE
of 2500-4500 J/kg) and favorable effective shear for supercell storm
structures capable of very large hail and perhaps a tornado or two.
Storms are expected to develop southward along boundary into central
SD during the evening, with gradual upscale growth into bowing line
segments. This activity will spread into western MN with the risk
of rather widespread damaging winds.
...Northeast WY/northwest SD...
A consensus of 12z model guidance shows a cluster of afternoon
thunderstorms forming over northeast WY and the Black Hills region.
Moisture is more limited in this area, yielding MLCAPE values only
into the 1000 J/kg range. However, steep lapse rates, cool
temperatures aloft (-12C at 500mb), and 30-40 knots of westerly flow
mid-level flow may result in a few supercells capable of hail and
damaging wind gusts.
...Southeast NE and vicinity...
Morning convection has resulted in an outflow boundary extending
from western MO into eastern KS. This boundary is forecast to drift
northward toward the KS/NE border by late afternoon, with forecast
soundings showing relatively large hodographs and strong instability
- posing a conditional risk of severe storms. However, no 12z CAM
guidance shows any thunderstorms forming in this area due to a
relatively warm capping layer. Have therefore removed the SLGT, but
continue to acknowledge the conditional risk of significant severe
weather if a storm can initiate/persist.
...GA/FL...
Numerous afternoon thunderstorms are expected from the FL peninsula
into central GA. A hot, humid, and very unstable air mass is
present in this corridor with dewpoints in the mid/upper 70s and
MLCAPE over 3000 J/kg. Shear is weak, but multicell storms capable
of locally strong/damaging wet microbursts appear possible.

Tropical Storm Celia Discussion Number 32
NWS National Hurricane Center Miami FL EP032022
900 AM MDT Fri Jun 24 2022
Little by little, Celia is becoming better organized. Deep-layer
shear has decreased markedly from a few days ago, but the cyclone
still appears to be in the process of mixing out some of the dry
air that got into the circulation. Subjective and objective
satellite intensity estimates now range from 55 to 65 kt, therefore
Celia's estimated intensity is increased to 55 kt on this advisory.
Celia is moving slowly toward the west-northwest (290/7 kt) to the
south of a mid-level ridge that stretches across the southern
United States and northern Mexico. The ridge is not particularly
strong, however, and this pattern is likely to cause Celia to slow
down further to around 5 kt during the next 12-24 hours. After 24
hours, the ridge is expected to strengthen and expand westward,
causing Celia to gradually accelerate through day 5. The guidance
envelope is tightly packed, and the updated NHC track forecast is
unchanged from the 09z forecast.
Shear diagnoses from the SHIPS model indicate that deep-layer shear
is likely to be less than 10 kt during the entire 5-day forecast
period. However, the limiting factor to Celia's intensity will be
sea surface temperatures. Celia still has an opportunity to
strengthen further, possibly to a hurricane, during the next 24
hours or so before it begins to cross the tight SST gradient near
Socorro Island. Gradual weakening is forecast after 36 hours over
colder waters, and Celia is likely to lose its deep convection and
become post-tropical by day 4.

Valid 241300Z - 251200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON
INTO TONIGHT FOR PARTS OF THE EASTERN DAKOTAS INTO NORTHWESTERN
MN...
...SUMMARY...
Severe thunderstorms with gusts up to 75 mph, very large hail up to
3 inches in diameter, and a couple of tornadoes are expected from
the eastern Dakotas into northwestern Minnesota this afternoon into
tonight.
...Northern Plains and vicinity this afternoon into tonight...
A corridor of low 70s dewpoints persists this morning from southeast
ND into central SD, to the east of a stalled front. Cyclogenesis is
expected today along the stalled front, as an upstream shortwave
trough moves eastward over MT, and a separate shortwave trough
ejects northeastward from UT/WY. The front will begin to move
eastward later this evening into tonight in response to the
approaching midlevel troughs, with scattered-numerous thunderstorms
expected along and ahead of the front across the central/eastern
Dakotas into northwest MN.
Surface heating within the moist, pre-frontal air mass, beneath very
steep midlevel lapse rates near 9 C/km, will result in MLCAPE of
3500-4500 J/kg. Convective inhibition will likewise weaken by mid
afternoon, when thunderstorm development becomes likely. The
stronger mid-upper flow will tend to lag west of the cold front, but
should be sufficient for supercells close to the boundary. The
large CAPE/steep lapse rate environment will support isolated very
large hail up to 3 inches in diameter and a couple of tornadoes with
the supercells, but there will likely be a tendency for fairly quick
upscale growth into clusters/line segments. Large CAPE will favor
precipitation loaded downdrafts and large DCAPE will favor intense
downdrafts, with the potential for swaths of damaging winds with
occasional significant (75 mph) severe outflow gusts late this
afternoon into early tonight as storms spread eastward from the
Dakotas into MN.
Other clusters of more high-based storms are expected to form
farther southwest across the central Rockies, and some of this
convection will move into the High Plains this evening in
association with the ejecting UT/WY shortwave trough. These storms
could be maintained long enough to reach the richer moisture/larger
CAPE in the vicinity of the stalled front, where large hail will
become more of a threat.
...Western GA into FL this afternoon...
A surface trough from western GA into north FL, along with daytime
heating and local sea breeze circulations, will help focus
thunderstorm development by early-mid afternoon. Strong surface
heating/mixing with hot afternoon temperatures, as well
boundary-layer dewpoints of 70-76 F, will support MLCAPE near 3000
J/kg this afternoon along the surface trough. The strong surface
heating will also drive steep low-level lapse rates, and DCAPE at or
above 1000 J/kg will favor occasional damaging gusts with downbursts
in south-southwest moving clusters of storms this afternoon/evening.

the eastern Dakotas into northwestern Minnesota this afternoon into
tonight.
...Northern Plains and vicinity this afternoon into tonight...
A corridor of low 70s dewpoints persists this morning from southeast
ND into central SD, to the east of a stalled front. Cyclogenesis is
expected today along the stalled front, as an upstream shortwave
trough moves eastward over MT, and a separate shortwave trough
ejects northeastward from UT/WY. The front will begin to move
eastward later this evening into tonight in response to the
approaching midlevel troughs, with scattered-numerous thunderstorms
expected along and ahead of the front across the central/eastern
Dakotas into northwest MN.
Surface heating within the moist, pre-frontal air mass, beneath very
steep midlevel lapse rates near 9 C/km, will result in MLCAPE of
3500-4500 J/kg. Convective inhibition will likewise weaken by mid
afternoon, when thunderstorm development becomes likely. The
stronger mid-upper flow will tend to lag west of the cold front, but
should be sufficient for supercells close to the boundary. The
large CAPE/steep lapse rate environment will support isolated very
large hail up to 3 inches in diameter and a couple of tornadoes with
the supercells, but there will likely be a tendency for fairly quick
upscale growth into clusters/line segments. Large CAPE will favor
precipitation loaded downdrafts and large DCAPE will favor intense
downdrafts, with the potential for swaths of damaging winds with
occasional significant (75 mph) severe outflow gusts late this
afternoon into early tonight as storms spread eastward from the
Dakotas into MN.
Other clusters of more high-based storms are expected to form
farther southwest across the central Rockies, and some of this
convection will move into the High Plains this evening in
association with the ejecting UT/WY shortwave trough. These storms
could be maintained long enough to reach the richer moisture/larger
CAPE in the vicinity of the stalled front, where large hail will
become more of a threat.
...Western GA into FL this afternoon...
A surface trough from western GA into north FL, along with daytime
heating and local sea breeze circulations, will help focus
thunderstorm development by early-mid afternoon. Strong surface
heating/mixing with hot afternoon temperatures, as well
boundary-layer dewpoints of 70-76 F, will support MLCAPE near 3000
J/kg this afternoon along the surface trough. The strong surface
heating will also drive steep low-level lapse rates, and DCAPE at or
above 1000 J/kg will favor occasional damaging gusts with downbursts
in south-southwest moving clusters of storms this afternoon/evening.
