Wish we could send some Redmond WA weather to cool things down in the hot part of the country. Over next 3 days we will have clouds, showers and a high temp in the low 70s.

@ingalls Most government web maps that display GIS data use ESRI software. That software makes a zillion calls to the ArcGIS server in order to do anything. Think 'bloatware'.

Below is a link to the 'lightweight' Leaflet web map I produce that displays the same data - in this case, all the weather watches and warnings.

Open the map, click colored area, follow the link. Since the spot you clicked might have more than one type of weather watch/warning, scroll down in the popup since each type of watch or warning has its own link for the details.

At the risk of tooting my own horn, GISsurfer has lots of features that are not apparent just by looking at the map. For both video and PDF tutorials see:

Mesoscale Precipitation Discussion 0203
NWS WOC College Park MD
325 PM EDT Wed Apr 30 2025

Areas affected...Central to NE TX...Far SW AR...Far
NW LA

Concerning...Heavy rainfall...Flash flooding likely

SUMMARY...A complex of heavy showers and thunderstorms will continue to gradually settle south and east going through the afternoon and early evening hours. Intense rainfall rates and storm totals will likely promote additional areas of flash flooding which will include locally considerable/significant urban flash flooding impacts.

DISCUSSION...The afternoon GOES-E visible satellite imagery shows a substantial amount of CU/TCU development across central to northeast TX out ahead of a well-defined and long-lived MCS that has been transiting northern TX and eastern OK over the last several hours. The warm-sector airmass with the aid of strong diurnal heating and a moisture-laden boundary layer with surface dewpoints in the upper 60s to low 70s is affording MLCAPE values as high as 1500 to 3000 J/kg. This includes the Austin to Waco corridor on northeastward up into the Tyler and Longview vicinity...
