Weather Headlines Thursday October 25, 2001 *** Powerhouse storm is about to exit. The coldest air of the season is about to enter. A significant warm up will commence late in the period.*** The "storm of the century", "Superstorm", or whatever you want to call yesterdays event was over-hyped a bit in my opinion, but significant in some respects. There were some large tornadoes in Northern Indiana and the surface low pressure center had one of the lowest readings I have seen in an October storm. Otherwise, it was a squall line of t-storms with a turn to colder and windier weather, things we have certainly seen before and will see again. The cold front should reach the Atlantic coastline later today and another line of t-storms may certainly go up along it. We also have some measurable snow in Minnesota this morning and could see "some" lake effect snows through Friday. Once this storm is off the field, the only inclement weather threats appear to be the PNW from a trough in the Gulf of Alaska and in Florida from something tropical. I do not mean from a named storm or hurricane, but merely that the disturbance originated in the Caribbean. A large polar air mass has swept in behind this storm insuring a drier and cooler than normal pattern from the Mississippi River and East through the weekend. The Plains start to warm early next week is ridging starts to evolve in response to troughing off the West Coast. Neither of these features look particularly strong in the short term and overall weather in the West has a benign look to it. I don't have a lot of change from yesterdays 6-10 day outlook other than advancing things by one day. Warming that kicks in for the Plains advances East. Relative to normal this will be more pronounced initially in the North than the South though by late in the period all will share. I mentioned an atmospheric turnaround yesterday and still feel there is potential by the middle of next week to become almost as warm as the recent warm episode. The pattern remains progressive, but not as volatile as recent weeks. Charts show another trough pushing through the Plains and Eastern U.S. but it does not have the amplitude that the current one does. Therefore, it can't tap the arctic air and bring it down. I have a fairly high confidence level that the first week of November will be mild for the nation as a whole. For the period October 25 through October 29, expect the following temperature trends: Average 7 to 9-degrees below normal: Great Lakes, Ohio and Mississippi Valleys... Average 4 to 6-degrees below normal: Plains, Northeast, Mid-Atlantic... Average 1 to 3 degrees below normal: Gulf Coast, Southeast, Rockies, Pacific NW... Average 1 to 3-degrees above normal: California, Intermountain West, Desert SW... Unspecified areas will average close to normal... Andy Weingarten, Meteorologist...
