An approaching front will cause scattered thunderstorms across the lower Midwest and Ohio Valley areas today. A few storms may be severe with hail and strong winds, and some locally heavy rain.
High temperatures will range from the mid-70s around the northern Great Lakes to the upper 90s on the western High Plains; most of the region will be in the 80s. Over the weekend a hot flow of air will bring temperatures well into the triple digits over much of the Central Plains.

Northeast
There will be a few thunderstorms across parts of southern Pennsylvania, Maryland, northern Virginia and West Virginia.  Temperatures will have highs ranging from the upper 70s in far northern New England to the mid-90s in Virginia.  A heat advisory has been posted for the Philadelphia metro area.

South
There will be scattered thunderstorms, especially from Mississippi to the Carolinas and across the Florida Peninsula. High temperatures could range from the mid-80s in the southern Appalachians and along portions of the eastern Gulf Coast to 100 degrees or more in parts of Texas; most of the Deep South will be humid with temperatures in the 90s.

Numerous Red Flag Warnings exist for parts of Montana, Wyoming, Nevada, and Oregon through the evening. There will be isolated thunderstorms across the Rockies. High temperatures will range from the cool 50s in the Washington Cascades to near 110 degrees in the lower Colorado River Valley.  (National Weather Service, Media Sources)

Midwest Flooding Update

Several rivers in Iowa, Illinois and  Missouri are above Flood Stage and Flood Warnings continue as a result of excessive runoff after multiple rounds of extremely heavy rainfall that began last week and continued last night. In north central Missouri, local law enforcement and Missouri Transportation Department officials continue to report state and county road closures due to flooding from area creeks, rivers and streams.

Mark Twain Lake, in northeast Missouri, is currently experiencing record high water due to ongoing heavy rainfall and river flooding in northeast Missouri. The U.S. Army Corp of Engineers is releasing 42,000 cubic feet per second of water out of Mark Twain Lake, resulting in flooding of low lying areas within the Salt River Basin.

Additional heavy rains could cause the Mississippi River to rise higher than expected. Due to runoff from rains that fell last week, area waterways in Missouri and Illinois will continue to run high. The Chariton River at Prairie Hill is experiencing record levels; however, the river is now receding and forecast to fall below flood stage on Friday, Aug 1. A second storm later in the week will increase the threat of flooding in the heartland. (NWS, Region VII)

New Mexico Flooding Update

Summary
Remnants from Hurricane Dolly dropped more than six inches of rain in south-central New Mexico July 27-28, causing flash flooding; the Ruidoso River rose several feet above flood stage.
One confirmed fatality is attributed to the flooding. One shelter is open with no residents. Of the 300-500 evacuees, most were vacationers. (NSS as of 4:45 p.m. EDT July 29)
Twelve to thirteen bridges, sixty percent of the secondary roads, and a sewer plant sustained damage from the flooding. Four dams are being inspected by the State Engineer's Office.
Two hundred to five hundred structures were damaged to include businesses along the Ruidoso River.

State and Federal Actions
Public Assistance is preparing a staffing plan for New Mexico with the potential of doing PDAs; two teams are on standby and ready to deploy.  FEMA Region VI is monitoring the situation and is in communication with New Mexico Department of Homeland Security and Emergency Management. However, Region VI has not received a request for federal assistance.  (NMDHSEM)

Louisiana Oil Spill Update

Louisiana Governor's Office of Homeland Security and Emergency Preparedness (GOHSEP) activated at Normal Operations, 7:30 a.m. - 4:00 p.m. CDT (M-F).
All channels are open and operating at normal pace; however, a safety zone remains in effect in order to control vessel wakes. All water intakes are confirmed open with water quality testing being conducted on both the intake and outtake points. Water is determined as being acceptable. No requests for Federal assistance received nor are any requests anticipated.

Clean-up and salvage operations are continuing and visible floating oil has decreased significantly. The U. S. Army Corps of Engineers (USACE) discontinued dredging operations in the "Head of Passes" area due to picking up oil into their hopper barge; the USACE will not resume operations until they can ensure oil will not be picked up. A total of 72,000 gallons of water/oil mixture has been recovered (an estimated 54,600 gallons evaporated from the water). (USCG Command Center HQs)

Telegraph Fire Update

Firefighters are continuing their efforts to contain a wildfire burning near a main entrance to Yosemite National Park since the weekend. The fire has burned 29,600 acres and is 15 percent contained; no acres have burned on the Yosemite National Park and the park remains open.

Twelve minor injuries and no fatalities have been reported. There are currently 71 crews, 408 fire engines, 59 dozers, 30 water tenders, and 3,458 total personnel assigned to this fire. The number of destroyed structures increased to 25 residences and 27 outbuildings.

The California OES, Inland REOC and State SOC are activated at the duty officer level. Mariposa County has activated their EOC and an OES representative is on scene. There are currently 3 shelters open in two counties with a population of 26 people. (NSS as of 4:45 p.m. EDT July 29)

PG&E shut down power lines into Yosemite Saturday because of the potential risk to firefighters working beneath the wires. The fire brought down a transmission line that carries electricity to the park. Media sources report that Pacific Gas and Electric (PG&E) restored power this Tuesday afternoon to many of homes and businesses that lost electricity because of the Telegraph fire. A PG&E spokesperson reported that PG&E is moving another generator into Mariposa County and hopes to restore some power on Wednesday to Yosemite National Park. (Media Sources)
