New SHORT TERM, LONG TERM, SPOTTER INFORMATION STATEMENT
SHORT TERM
(Wednesday through Thursday)
Issued at 216 AM CDT Wed May 21 2025
Well, in previous discussions during this busy string of overnights stated that Wednesday and Thursday were supposed to be quiet after a week of strong to severe storms of at least parts of our area. The good news is that today is still supposed to be quiet in terms of thunderstorms. In fact, I am not even sure we will see much in the way of cloud cover today across much of the area. Temperatures today will be slightly above seasonable normals with highs ranging from the mid 80s across our northern zones to around 90 degrees across our southern zones. Lows tonight will be seasonable as temperatures dip into the upper 50s across our northern zones to the lower and mid 60s elsewhere.
On Thursday, upper-level ridge will begin to build into the southwest CONUS while troughing remains in place across the eastern CONUS. This will result in northwest flow aloft across our region. Meanwhile at the surface, a warm front will be lifting northward through our area. Models tonight have picked up on some indication of some thunderstorm development across our far northwest portion of the forecast area of northeast Texas, southwest Arkansas and southeast Oklahoma. Thinking that most of the storms will be elevated in nature and pose more of a damaging wind and hail threat. In response to these new model runs, SPC has introduced a Marginal Risk for severe storms for areas along and north of a line from near Tyler, TX to just south of Texarkana.
HRRR is showing some thunderstorm develop during the late morning hours on Thursday across central Oklahoma that will dip southward into our area by around noon, with some additional development during the afternoon hours across northeast Texas. Granted, timing is always subject to change some, so be sure to follow the forecast for the latest information. /33/
LONG TERM
(Thursday Night through Wednesday)
Issued at 216 AM CDT Wed May 21 2025
Northwest flow aloft continues across the region as we move into the long-term portion of the forecast as the upper-level ridge slowly builds to the west into Sunday. As is common with northwest flow aloft, we get a more unsettled weather pattern. Still thinking that any thunderstorms that should or could develop on Friday and Saturday will mainly impact our northern zones. A trough will begin to develop and move into the central CONUS on Sunday and into the start of next week that could bring some more widespread showers and thunderstorms to the area. /33/
AVIATION
(06Z TAFS)
Issued at 1140 PM CDT Tue May 20 2025
Cold front has just about moved through our entire airspace late this evening with only a SCT/BKN CU field noted from Deep East Texas to south of the MLU terminal. Thin cirrus will increase during this TAF period but VFR conditions should prevail through the next 24 hours. Look for mostly variable to southeast winds today with speeds under 10kts.
