ssued 622pm CDT Tuesday May 17 2022/... .SHORT TERM [Tonight through Tomorrow/Wednesday Night]... Very warm temperatures along with very limited rain chances will be on tap for the short term given the flat mid/upper ridge in place a- cross the region. We could see some patchy low clouds/fog overnight through the very early morning hours but should be short-lived with the development of slightly elevated winds/gusts by tomorrow after- noon. This slightly tightened gradient (via a well-defined shortwave moving across the Central Plains) is expected to remain in place as this week progresses. High clouds are also set to increase tomorrow with the subtropical jet. Lows tonight and tomorrow night are going to range from the lower to mid 70s for most inland locations to the upper 70s at the beaches. Highs tomorrow will be in the mid 90s for areas generally along and north of I-10, and lower 90s to upper 80s south to the coast. 41

.LONG TERM [Thursday Through Tuesday]... Very warm to hot afternoon high temperatures (including heat index values back close to or exceeding the century mark) can be expected Thursday and Friday and could also creep into Saturday. For the first two days, weak disturbances will be moving eastward across the state, but moisture levels will remain limited (just the usual mainly late night through early morning low clouds, plenty of afternoon sunshine and a breezy to possibly windy southerly flow). Weakness aloft along with more embedded impulses will be working across the area with gradually increasing/deepening moisture levels and a late season cold front to bring parts of the area some rain chances mainly in a late Friday night or Saturday through the first half of next week time period. Best rain chances look to probably be setting up in the Saturday afternoon through early Sunday morning time period in association with the cold front that will be moving into and through the area. Enough cooler and drier air should settle into the area behind this front resulting in lower Sunday and Monday afternoon highs (80s instead of 90s!). The cold front will move back inland and through the area as a warm front on Monday and Monday night. Expect a gradual rising temperature trend beginning on Tuesday.

Marine
Strengthening south to southeast winds and building seas can be expected through the end of the week as the pressure gradient tightens. Caution flags have been issued for most of the area beginning this evening, and upgrades to advisories for parts of the area can be expected through the end of the week as winds continue to increase and seas begin to build. A slightly weaker and more east to northeast flow along with lowering seas are anticipated to develop Saturday night and Sunday as a cold front moves into the area. Look for increasing shower and thunderstorm chances with this front.

Climate
Galveston's low temperature so far today has been 77 degrees. This will only be the 5th time so far this month that no daily record high minimum temperature record has been tied or broken (today's record is 79 degrees set in 2017). Included in those 12 records that have been set so far this month is a low of 81 degrees on the 9th which tied May's all-time record high minimum temperature. Thru the 16th, Galveston's average minimum temperature is 78.1 degrees and is 2.1 degrees above the previously warmest May 1-16 period set in 2009 and also in 2003.
