Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 321 AM EDT Wed Oct 3 2018 Valid 12Z Wed Oct 3 2018 - 12Z Fri Oct 5 2018 ...Rapidly developing surface low tracks across the Great Lakes, with warm weather across the central and eastern states... A potent shortwave trough crossing the northern plains and south-central Canada will support the rapid development of a strong surface low from the Upper Midwest to Ontario through Wednesday. This low is forecast to undergo explosive cyclogenesis as it tracks northeastward towards northern Quebec by Thursday, with a pronounced cold front trailing it. This strong front will then sweep across the Great Lakes into New England by Thursday afternoon. Big temperature changes are expected with the passage of this front, with the much above average temperatures Wednesday over the central and northern plains being replaced by below average temperatures on Thursday in the wake of this front. This cooling trend will then reach into New England by Friday. To the south and east of the above mentioned strong cold front, widespread readings in the 85 to 90 degree range are likely from the Southern Plains to the Ohio Valley on Wednesday, with anomalies up to 20 degrees above normal for early October. On Thursday, readings are forecast to be only in the 40s for daytime highs across the northern plains and into Minnesota, making it feel more like November. Areas of moderate to heavy rain are likely across the Great Lakes region in association with the surface low and cold front passing through. D.
