...Tropical Storm Idalia to impact much of Florida and the Southeast Coast
this week...

...Scattered showers and thunderstorms likely across the Central/Southern
High Plains, Southeast and the Mid-Atlantic today...

...Pacific Northwest begins to cool down while Southwest experiences
anomalous warmth...


Tropical Storm Idalia is forecast to bring heavy rainfall, strong winds,
significant storm surge, and thunderstorms to parts of the Florida Gulf
Coast beginning Tuesday night. Portions of the west coast of Florida, the
Florida Panhandle, Southeast Georgia and the eastern Carolinas could
receive 4-8 inches of rainfall by Thursday. Isolated higher totals of 12
inches are possible, primarily near landfall in northern Florida. A
Moderate Risk of Excessive Rainfall leading to Flash Flooding is in effect
for this part of northern Florida on Tuesday. Areas of Tropical Storm
Watches and Warnings, and Hurricane Watches are in effect across much of
the Florida Gulf Coast. For more information on Idalia go to
hurricanes.gov.

A quasi-stationary front, currently draped across the lee of the Southern
Appalachians down through the central Gulf Coast will be the focus for
rounds of afternoon/evening convection today. A broad Slight Risk area is
in effect from southern Virginia to northeastern Alabama, where convection
enhanced by upslope flow over the Southern Appalachians could pose flash
flooding concerns with rainfall rates between 1-2in/hr.

A persistent ridge in the Southwest will contribute to anomalously warm
temperatures
