Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 434 PM EDT Mon Aug 03 2015 Valid 00Z Tue Aug 04 2015 - 00Z Thu Aug 06 2015 ...Severe weather possible from the Ohio valley into interior New England... ...A threat for flash flooding exists from the Texas/Oklahoma panhandles toward southeastern Kansas/western Missouri... ...Above normal temperatures return to the Southern High Plains by mid-week... A broad upper low centered just south of Hudson Bay will be slow to move eastward in the next couple of days. Multiple embedded impulses will migrate toward the eastern U.S. with a threat for showers and thunderstorms along and ahead of the parent cold front. This boundary is expected to be rather slow moving with convection occurring in the moist/unstable air mass out ahead. Severe thunderstorms are possible along all of interior New England and stretching down into southern Ohio/northern Kentucky through Tuesday morning. By the following day, expect the activity to be less concentrated and a bit more disorganized as the core of stronger dynamics remains well to the north. Elsewhere, multiple lobes of energy meandering about the Central Great Basin/Central Rockies region continue to spawn showers and thunderstorms in its vicinity. Overall rainfall amounts should be heaviest in the upslope topography. Eventually one of these disturbances will emerge off the Front Range of the Rockies and begin to interact with a well defined moisture plume moving through the Great Plains. It appears a rather organized area of convection should move through the Texas/Oklahoma panhandles later this evening and into the overnight hours. High rainfall rates combined with saturated soils may increase the threat for flash flooding across the aforementioned panhandle regions of Texas/Oklahoma. Eventually this activity should weaken by Tuesday morning before re-organizing later in the evening across southeastern Kansas. Strengthening of this convection should support an additional flash flood threat across southeastern Kansas/western Missouri through Wednesday morning. A stalled frontal boundary anchoring the central/eastern Gulf Coast region will maintain a threat for thunderstorms, particularly in locations near the coast where local sea breeze effects will come into play. Back to the west, a building upper ridge over the Four Corners region/adjacent Southern High Plains will bring above normal temperatures back to the region by mid-week. Expect readings approximately 5 to 10 degrees above normal which supports temperatures around the century mark. Rubin-Oster Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
