Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Thu Sep 09 2021 Valid 12Z Thu Sep 09 2021 - 12Z Sat Sep 11 2021 ...Tropical Storm Mindy is forecast to move across Georgia this morning with gusty winds and a period heavy rain before moving out to sea this afternoon and tonight... ...Scattered thunderstorms slowly move across the Eastern Seaboard today... ...There is a Slight Risk of excessive rainfall over parts of the Florida Panhandle through Thursday morning... ...The current heat wave in the western U.S. will shift into the central High Plains by Friday as scattered thunderstorms move across the interior northwestern U.S.... A cold front will continue to slowly edge eastward across the Eastern Seaboard today. Thunderstorms associated with the front will be scattered along the East Coast and will be slow to exit the region today. Meanwhile, Tropical Storm Mindy that formed yesterday afternoon in the Gulf of Mexico is moving across Georgia early this morning, bringing gusty winds and a period heavy rain to the north of the storm track while scattered thunderstorms develop south of the track over northern Florida. The cold front is forecast to gradually move off the East Coast tonight. This will push Mindy off the coast of southeastern U.S. together with the rain and thunderstorms along much of the East Coast later tonight. Over New England a low pressure wave forming along the front will impede the eastward progress of the front, and thus keep the rain in the area into Friday. Elsewhere, an upper-level high over the Great Basin will aid in producing record high temperatures over the Western States through Thursday, then over parts of the Central Rockies and the Central/Southern High Plains on Friday. Furthermore, the dry weather associated with the upper-level high will and gusty winds has led to an increase in the fire weather threat over parts of the Northern Intermountain Region/Northern Rockies as a Critical Risk of fire weather is posted. Red Flag Warnings over parts of the Northwest into the Northern Rockies and Northern High Plains. In addition, Excessive Heat Warnings are posted over Southeastern California, southern Nevada, and parts of northwestern Arizona. Heat Advisories are also issued over most of California. However, Air Quality Alerts have also been published over parts of the Pacific Northwest, Idaho, Wyoming, and Colorado due to wildfire smoke.
