Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 328 AM EDT Tue Sep 19 2017 Valid 12Z Tue Sep 19 2017 - 12Z Thu Sep 21 2017 ...Hurricane Jose will produce dangerous surf conditions and rip currents along with heavy rainfall across the Northeast... ...Severe weather possible across the northern Plains... ...Snow possible in the higher elevations of the Cascades and Northern Rockies... Hurricane Jose will continue moving in a northwest track while staying well of the East Coast of the U.S. However, dangerous surf conditions along with the threat of rip currents will be possible from the North Carolina coast into New England. In addition, heavy rainfall from Jose will begin to increase across southern New England by Tuesday afternoon. These rainfall amounts will increase especially in coastal New England through Wednesday morning. By Wednesday evening, rainfall coverage will decrease and completely taper off by Thursday morning. There is a slight chance of flash flooding for southern New England on Tuesday. For the most current information, see the National Hurricane Center (www.hurricanes.gov). A strong cold front ejecting into the northern Plains by Tuesday afternoon will bring with it showers and thunderstorms. This line of convection will begin firing off on Tuesday evening and continue overnight as it moves into the Upper Midwest. There is an enhanced risk of severe weather in the eastern portions of the northern Plains and parts of the Upper Midwest in addition to a marginal risk of flash flooding. As the cold front extends from the Upper Great Lakes and into the middle Mississippi Valley on Wednesday, the line of showers and thunderstorms will also move across these areas. There is a marginal risk of severe thunderstorms in these regions. For more information regarding severe weather associated with this system, please see the Storm Prediction Center (www.spc.noaa.gov). Prior to the strong cold front that will cause the severe weather in the northern Plains, it will move through the Intermountain West by Tuesday morning. Behind it, widespread precipitation is expected across the Pacific Northwest and Northern Rockies is expected. Another front will approach the Pacific Northwest coast by late Tuesday night which will bring more precipitation to this region. This front will move through the Pacific Northwest overnight, and by Wednesday it will continue moving through the Intermountain West. Heavy rainfall will follow it across both of these regions. On Thursday morning, precipitation amounts will decrease in the Pacific Northwest and parts of the Northern Rockies. However, precipitation near the front will still give way to heavier amounts. Higher elevation snow is expected during the short term period along the Cascades and the Northern Rockies; however, snowfall in the Cascades will begin to taper off during the day on Thursday.
