Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0540 AM CST Thu Mar 02 2017 Valid 021200Z - 031200Z ...Synopsis... Broad mid-level cyclonic flow will be established across much of the eastern US today. Embedded within this flow, one impulse will lift northeast from New England into the Canadian Maritimes while another will drop southeast from the northern Plains to the Ohio Valley. At the surface, a cyclone will deepen as it advances northeast into New Brunswick. In its wake, high pressure will build across much of the eastern US. Farther west, a weak migratory low will progress from the central Plains to the mid Mississippi Valley, in response to the aforementioned impulse. ...Portions of the central Plains and Ozarks... A small corridor of enhanced west/northwesterly 850-mb flow will accompany the passing wave over the region today. In combination with some modest tightening of the surface pressure gradient both ahead and behind the surface trough, this flow aloft will lead to breezy conditions across the region, with sustained west/northwesterly winds around 15-20 mph. With dry air well established, RH values will likely fall to around 15-25 percent as well. Sufficiently dry fuels are expected to be available, such that these meteorological conditions will likely favor elevated fire-weather concerns. ...Portions of the Southeast... Within a post-frontal dry air mass, RH values will fall to around 25-35 percent across much of the region today. While northerly winds around 10-15 mph may locally enhance fire-weather concerns, they should remain marginal enough to preclude highlights, especially considering recent rainfall in many locations. ..Picca.. 03/02/2017 ...Please see http://ift.tt/2i2um2s for graphic product...Read more
