Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 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 northward well off the Northeast coast. Despite its lack of proximity, Jose will bring heavy rainfall to the Northeast and southern New England coastlines. Coverage of precipitation will increase this morning and into the evening. By Thursday, precipitation will completely taper off the New England coast. There is a slight risk of flash flooding with this heavy rainfall. In addition, dangerous surf conditions and rip current threat will still exist from the beaches of North Carolina to New England. For more information on Jose, please refer to the National Hurricane Center ( A line of thunderstorms will push across the Upper Midwest through Wednesday morning. However, by Wednesday afternoon, the axis of heavy rainfall will move into Canada as the occluded front lifts northward. Showers and thunderstorms will continue firing off along the cold front that will extend from the Upper Great Lakes to the central Plains. However, this thunderstorm activity will only have a marginal risk of severe weather. By Thursday, light showers will linger along the Upper Great Lakes. Expect more rounds of convection for the Upper Midwest by Friday morning ahead of another impending cold front with a slight risk of severe weather extending from the Upper Midwest to the eastern portions of the northern Plains. See the Storm Prediction Center ( for more information in regards to severe weather. 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. Ziegenfelder Graphics available at
