/Issued 1153 AM CDT Sun May 12 2024/ Rain and thunderstorms developed as expected this morning with some overachievers across Central Texas where instability and deep layer shear was the strongest. 2 inch hail was reported across portions of Bell County earlier with smaller hail reports in other counties. Along with the hail we have had some heavy rainfall with 2 to 3 inch amounts between the Colorado River and the Brazos river across Central Texas. We expect periods of rain and thunderstorms to continue through the afternoon due to passing shortwave energy and a lifting warm front. Precipitation will taper off from southwest to northeast through the afternoon and into the evening once the center of the shortwave circulation moves into the Central Plains and the warm front moves northeast towards the Red River. Most of the CAMS agree that precipitation will temporarily end this evening/overnight for much of the CWA, but rain and storm chances will return on Monday with the arrival of a cold front. Some of these storms will become strong to severe with the best chances across our Central Texas counties where the air will be most unstable. The main threats will be from large hail and damaging winds. The front will exit the region Monday evening, bringing an end to the precipitation until the middle of the week, as discussed in the long term discussion below. Temperatures this afternoon will be rather cool due to the rain and extensive cloud cover with most spots not getting out of the 70s. Clouds and patchy fog are expected tonight behind the rain which will keep temperatures in the 60s. Morning clouds on Monday will decrease from west to east through the day as drier and subsident air filters in behind the cold front. Afternoon sun will offset very weak cold air advection, allowing temperatures to warm into the 80s. Drier air and a clear sky Monday night will result in cooler temperatures with upper 50s across the west and northwest and lower to middle 60s elsewhere. 79

/NEW/ /Tuesday through Sunday/ Ridging aloft will fill in behind the departing shortwave on Tuesday, resulting in plenty of daytime sun and afternoon highs in the 80s. Subsidence under the ridge will remain through Wednesday morning but the ridge axis will shift quickly eastward Wednesday afternoon ahead of another developing shortwave across the Desert Southwest. Thunderstorms will form along the dryline across West Texas Wednesday afternoon but these storms will not reach the CWA until Wednesday night when the shortwave deepens and moves into the Four Corners region. Showers and thunderstorms will be likely through Thursday with the passage of the trough axis followed by another cold front. It is difficult to say what the extent of severe weather will be Thursday but given the pattern, some severe storms could certainly be possible. Precipitation will end from west to east Thursday night once drier air moves in behind the front. The drier air will be very temporary and moisture will return Saturday in response to a weak shortwave following on the heels of the late week system. Although we are not seeing overly strong signals in the long range models for thunderstorms on Saturday and Sunday, there is enough moisture and lift indicated to keep slight chances mentioned. Temperatures Tuesday through the weekend will be near or above seasonal normals overall with highs in the 80s and lows in the 60s. The only exception will be on Thursday when clouds and rain will keep highs in the 70s. 79

/Issued 1153 AM CDT Sun May 12 2024/ /18Z TAFs/ Rain and thunderstorms will move across all TAF sites through the afternoon with the best window of time for storms between issuance time and about 23Z. Some showers and storms will linger in the vicinity until about 01Z. MVFR to IFR ceilings and visibility will accompany the storms. There will be a brief improvement to ceiling heights after the rain moves to the northeast but ceilings will fall again late this evening and overnight along with patchy fog. Additional showers and thunderstorms will be possible Monday morning with the arrival of a cold front but all precipitation will shift southeast of D10 airspace by afternoon. The prevailing wind through tonight will remain southeast between 6 and 12 knots except for gusty and erratic winds in and near any thunderstorms. A west to northwest wind will follow the passage of the cold front Monday but wind speeds should not be strong enough to cause any crosswind issues. 79
