Strong autumn cold front to bring wind and another round of storms


After a nice rain yesterday (most areas received anywhere from 0.50"-2.00" of rain Sunday), another round of storms will be knocking on our doorstep early Tuesday. A very strong low pressure system will explode over the Northern Plains tonight (see the first map above, valid at 7am Tuesday). That low will quickly usher through a cold front that will blast through the region during the morning hours.

Due to the strength of the entire system, high wind will be the primary threat, even before the storms get here. Southerly wind will gust above 30 mph, perhaps with isolated gusts to 40 mph, after midnight tonight through the mid-morning hour tomorrow. As the front nears, a squall line is expected to form and race through the region. The wind driving the front will be blowing at near 70 mph in the lower levels of the atmosphere and some of this wind could get pushed near the surface in the storm downdrafts, bringing a threat of isolated damaging wind gusts. For this reason, the Storm Prediction Center has issued a SLIGHT RISK of severe weather for the metro area for tomorrow morning (see map 2 above).

Behind the front, skies may clear briefly, but expect a mostly cloudy day with wind diminishing during the afternoon and temps falling through the 60s.
