KEY MESSAGES: - A slow warm up is expected through Sunday when 90s for highs will again appear. - Next round of hit and miss rain showers are expected to begin Thursday afternoon and last through Saturday Morning. WEATHER PATTERN OVERVIEW: After a dry day today, zonal flow along the northern CONUS will continue to allow weak shortwaves to move through the area from Thursday afternoon to Saturday morning. This will produce hit-and- miss showers and thunderstorms during this time. Most common area totals range from a quarter-inch to three-quarters-inch for areas hit during this group of periods. Mainly general thunder is expected with any storms as they will be embedded in rain showers. FORECAST CONFIDENCE and DEVIATIONS: Isolated morning fog along the Missouri Valley may be possible today but does not look likely (<20% chance). So low confidence. All fog chances should be over by 9AM. Currently, there are no major signatures for severe weather Thursday afternoon to Saturday morning in the synoptic scale for the ensembles. However, this is just beyond the range of CAMs, so that could change. High confidence(50-80%) in general thunder. Very minimal chance(10%) for any severe wx during this group of periods.
