We continue to watch the chance for a potent storm across the Midwest on Christmas day. Models seems to be locking in on a track, but there are differences with timing. The models still have a large storm system affecting the West Coast Friday through Saturday, closing off over the Rockies, then move into the Plains Sunday and Sunday night.
Models continue to trend warmer with each model run. With much warmer air being drawn into the the storm system, this will result in precipitation being all rain, and the potential will exist for a few rumbles of thunder. Highs on Sunday will be in the 40’s and 50’s, with the potential for a few 60’s across southern Iowa.
Rainfall totals will also be impressive. Rainfall amounts of a half inch to as much as an inch will be possible Sunday into Monday. There is a chance that a few storms may be strong to possibly severe. This threat will be something we keep an eye on, as it is still early in the game.
This system is still off of the west coast, so right now, we are in a wait and see mode. Continue to follow IowaChase.com for the latest updates.
