Tropical Depression Cristobal has continued to move well inland across northern Missouri this afternoon, bringing tropical downpours and gusty winds near its track. The depression is expected to move steadily toward the north-northeast across the Midwest and into the upper Great Lakes tonight, while finally losing its tropical characteristics. In the mean time, a sharp cold front in conjunction with an anomalously deep and energetic upper trough is pushing eastward across the Plains. A complex interaction among Cristobal, the sharp front, and the deep upper trough will result in a variety of active weather from the central to the northern portions of the country through Wednesday morning. Strong to severe thunderstorms are possible across the central Plains behind the sharp front bringing a quick burst of strong gusty winds. Heavy rain associated with the influx of tropical moisture will result in possible flash flooding from northern Kansas to Wisconsin. Meanwhile, once Cristobal reaches the Upper Great Lakes region tonight, it is forecast to intensify as a post-tropical storm as the energetic upper trough approaches from the west. Winds are forecast to reach gale force over the waters of the Great Lakes as the system passes in a close distance early on Wednesday. The Great Lakes will continue to see showery and windy conditions into Wednesday as the complex system intensifies further and heads into eastern Canada early on Thursday. The southern portion of the strong front moving through the Plains is not expected to have much precipitation associated with it today. However, in its wake, windy conditions are likely across the southern High Plains and into Southern California. The combination of these high winds and low relative humidities will produce elevated to critical fire weather conditions across these areas. The threat for severe thunderstorms will shift east on Wednesday across the Ohio Valley, Lower Great Lakes, and Interior Northeast. A potent cold front will be the trigger for these storms, with strong winds and isolated tornadoes possible mainly across lower Michigan and Ohio. This front will slowly push towards the East Coast coast on Thursday, bringing the chances of showers and isolated thunderstorms. Temperature-wise, the widespread below average temperatures currently across the Rockies and High Plains will push eastward behind the above mentioned strong cold front and into the central/northern Plains tonight and into the Upper to Mid Mississippi Valley on Wednesday. Above normal temperatures are expected across the southern Plains today followed by a general cool down. Hot and humid tropical air brought by Cristobal will overspread large portions of the eastern U.S. before cooler air filters in from west to east behind the sharp cold front.
