Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 500 AM EDT Tue Jul 29 2014 Valid 12Z Tue Jul 29 2014 - 12Z Thu Jul 31 2014 ...Heavy rains and flash flooding expected across eastern Colorado and much of Oklahoma... ...Below normal temperatures will continue beneath a broad trough carved out over the eastern half of the Nation... Widespread showers will continue across the central Great Basin and central/southern Rockies the next few days. Much of the activity should be scattered in nature...but anomalous moisture trapped over the region could lead to locally moderate to heavy rains. Slightly farther east...energy diving southeastward through the central Rockies will help organize an area of heavy rains and thunderstorms to the north of a surface low and frontal boundary strengthening over the Colorado Front Range Tuesday afternoon. Although the drought stricken areas could use the precipitation...locally heavy downpours could lead to flash flooding. The heavy rains and threat for flash flooding will spread across much of Oklahoma as the energy aloft continues its southeastward trek Tuesday night into Wednesday. Below normal temperatures will continue beneath a broad and anomalous trough carved out over the eastern half of the Nation. Much of the east will stay precipitation free; however...a cold front dropping down from Canada will trigger scattered showers and thunderstorms across the Great Lakes region. Also...scattered convection will continue over Florida and the Gulf Coast the next few days...to the south of a frontal boundary plunged across the southern tier of the Country. While the east remains relatively cool...an amplified upper ridge will keep temperatures above normal over the northern Rockies and Intermountain West. Heat advisories have been issued for portions of Washington state...where daytime temperatures will soar into triple digits and overnight lows will barely drop out of the seventies.
