Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 435 PM EDT Wed Sep 20 2017 Valid 00Z Thu Sep 21 2017 - 00Z Sat Sep 23 2017 ...Tropical Storm Jose will produce dangerous surf conditions and rip currents along with heavy rain over parts of Southern New England Coast... ...There is a slight risk of severe thunderstorms over parts of the Upper Great Lakes/Upper Mississippi Valley... ...Heavy snow possible in the higher elevations of the Northern Rockies... Tropical Storm Jose will continue to weaken as it moves northeastward then returns southwestward while remaining off the Northeast coast. The storm will produce rain with embedded thunderstorms over parts of Southern New England Coast through Friday. For more information on Jose, please refer to the National Hurricane Center (www.hurricanes.gov). A front extending from the Upper Great Lakes/Upper Mississippi Valley southwestward to the Southern Plains will move eastward into the Great Lakes/Middle Mississippi Valley and dissipates on Thursday afternoon into evening. Showers and thunderstorms will develop over parts of the Upper Great Lakes/Middle Mississippi Valley that will move into the Great Lakes/Middle Mississippi Valley overnight Wednesday while dissipating over the Middle Mississippi Valley by Thursday afternoon. The showers and thunderstorms will continue over parts of Northern Michigan through Friday. Another front over the Northern Rockies/Northern High Plains into parts of the Great Basin/Northern California will move to the Upper Mississippi Valley and the Northern/Central Plains into the Central Rockies/Great Basin by Friday. The system will produce rain with embedded thunderstorms with snow at the highest elevations over the Northern Rockies and rain over the Pacific Northwest that will wane over the Northwest by Thursday morning. The rain with the higher elevations snow over the Northern Rockies will continue through Friday. The active stormy pattern for the Pacific Northwest and Intermountain West will continue through the short term period. Heavy rainfall is expected throughout the Pacific Northwest and into the Intermountain West on Wednesday with higher elevation snow for the Cascades and Northern Rockies. By Thursday, rainfall activity will decrease in the Pacific Northwest while increasing across the Central Great Basin. Snowfall will also be possible in the higher elevations of the northern Rockies, Utah, Nevada, and even the highest peak in the Sierra Nevada mountains on Thursday. By Friday morning, precipitation will move eastward across the northern Rockies and Great Basin. Elsewhere, locally heavy rainfall can be expected for south and central Texas on Thursday as deep moisture feeds across the state. The Gulf coast can also expect scattered showers and thunderstorms especially on Thursday--with locally heavy rainfall possible in the southern half of Florida.
