.DISCUSSION... Issued at 1228 PM CDT Sun Sep 28 2025
For the most part, high pressure anchored over the eastern CONUS will be in control of our weather through the upcoming work week, and no significant frontal passages are expected. The upper level trough that is helping to keep what is currently Tropical Storm Imelda off the southeast coast could bring some very light convective rainfall later this week (mainly Wed/Thu afternoons), but rain chances overall will remain low. Confidence is high that we will see drier and slightly cooler air advect into our region on the left side of "Imelda" by late in the week and next weekend. Given the long duration stretch of below normal rainfall observed, we will be monitoring for any increased fire weather threats in this dry weather pattern. As of now, the RH/Wind forecast elements look like they should remain below critical thresholds. /EC/
