Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 305 AM EDT Mon Jul 24 2017 Valid 12Z Mon Jul 24 2017 - 12Z Wed Jul 26 2017 ...Localized flooding will be possible for the Southwest and southern and central Rockies over the next few days... ...Severe weather and flash flooding possible across parts of the northern Plains and upper Mississippi Valley on Tuesday... Widespread showers and thunderstorms are expected across the Southeast with hot and humid conditions in place ahead of the approaching cold front. The front will stall from the central Plains to the Mid Atlantic, so shower activity will continue into Tuesday. Further north, low pressure sliding off the Mid Atlantic coast will bring some heavy showers and thunderstorms across southern New England before pushing well offshore. Monsoonal moisture will fuel daytime thunderstorm activity across the Southwest on Monday and Tuesday. The initial surge on Monday will support more widespread activity with moisture waning by Tuesday. Locally heavy rainfall will have the potential to cause flash flooding across the desert Southwest and central/southern Rockies on Monday. With the upper level pattern shifting a bit further north, shower activity will spread into the Great Basin and northern Rockies, though more limited moisture will cut back on the extent of rainfall. However, some flash flooding will still be possible across the central Rockies and Great Basin. Conditions will become favorable for severe weather and flash flooding across parts of the northern Plains and upper Mississippi Valley by Tuesday. A cold front will push across the northern tier, with southerly flow taking hold across much of the central U.S. This will allow heat to build and moisture to pool along and ahead of the frontal boundary. Showers and thunderstorms are expected to break out across the northern Plains and upper Mississippi Valley. The upper level pattern will become more favorable by Tuesday, supporting more organized thunderstorm activity. Krekeler Graphics available at
