More Than 6" of Rain Overnight and Today's Flash Flood Outlook

Image
 The forecast (posting below) turned out to be correct as more than 6 inches of rain fell overnight in small parts of northern Missouri and southern Iowa (red). New Mexico is also at risk of serious flooding.  24 hour rainfall ending at 9am CDT There is a moderate risk of more heavy rains in the region today so additional flash flooding is possible.  The red area in New Mexico has a high  risk of additional flash flooding today. Remember: whatever you do, don't try to cross flooded areas by foot or by car.

Updated Freezing Rain and Heavy Rain Forecast

Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches.

Heavy Rains California and South

In addition to the risk of an ice storm in the southern Great Plains, there are two areas where excessive rainfall are forecast to occur. Texas and Louisiana More than seven inches are forecast to fall the next week from near Houston/Galveston to Lake Charles to Alexandra. Normally, I would be predicting flooding but much of that area is extremely dry The reds and browns are the driest.  West Coast The lightest yellow is more than ten inches of precipitation, mostly snow. At lower elevations, more than five inches are forecast to fall as far south as Carmel. This weather system will be far enough south to cause significant rains over the Baja desert.  Above is a map from the NWS which indicates where flooding may occur -- on a scattered basis -- from tomorrow (Saturday) through Monday.
