Short Range Forecast Discussion...amended NWS Weather Prediction Center College Park MD 701 AM EDT Tue Sep 16 2014 Valid 12Z Tue Sep 16 2014 - 12Z Thu Sep 18 2014 ...Heavy rain/flash flooding expected across the Southwest/Southern Rockies... A quasi-stationary front extending from the southern states to the Southern Plains will focus showers and thunderstorms across the region through Wednesday. Meanwhile, upper-level energy over the Northeast will aid in producing rain over the area on Tuesday morning, which should wane across portions of Maine by Tuesday evening. A front moving southeastward out of Central Canada will move into the Great Lakes and Northern New England Tuesday evening into Wednesday evening. The boundary will produce light rain over parts of the Upper Great Lakes from early Wednesday morning to Wednesday afternoon. The big story will concern moisture moving northward from the Gulf of California and westward from the Gulf of Mexico/Texas associated with the circulation around Tropical Storm Odile. Showers and thunderstorms with heavy rainfall over expected parts of the Southwest, Southern Rockies, and into parts of the Great Basin through Wednesday evening. Low-level inflow combined with daytime heating should be sufficient to organized thunderstorm activity over the next few days, bringing locally heavy rain with amounts which could challenge the annual average rainfall across the Desert Southwest, similar to what was seen around the periphery of Norbert eight days ago/on September 8.
