.. NWS/Storm Prediction Center Issues Severe Thunderstorm Watch Until 4am
for IH35 Corridor Counties Westward ..
Kimmel Note: Please keep in mind that we’re right on the eastern edge of this watch..
even though it’s possible some discrete cells ahead of the line may affect some areas
(still with a severe risk), it is unlikely that the main line of thunderstorms will affect our
area until after 2am (at least).. keep in mind that, by the time that weather affects our
area and assuming it maintains its intensity, it is likely a new watch will be needed for
the areas along and east of IH35…
Here is where we are in reference to the watch box and details below…
