Warmer Temperatures/Fog Expected Today

Warmer Temperatures And Fog Expected Today

South winds will reinforce the mild air mass over the region through this evening. Highs today will range from the lower to the mid 50s. A strong cold front should then move through the area late this evening, with windy conditions expected Friday. Highs will reach the upper 30s to mid 40s early Friday, with falling temperatures through the day.



The warmer and more humid airmass moving over the melting snowpack will bring areas of fog today, with isolated areas of dense fog, as well as drizzle and a chance for rain. These conditions may last into this evening, before the strong cold frontal passage. In addition, the melting snow on frozen ground may lead to runoff and slow rises in area rivers and streams.  In addition, as ice breaks up in the rivers, it can cause temporary ice damming and localized flooding.  Right now, it does not appear that any flooding is imminent. 


The 2-image animation below shows the damage that was done to the widespread snowpack that existed across a large part of the U.S. late last week.  You can see from the February 11th image, that the snow cover stretched out to the Rockies and as far south as Texas, Oklahoma, Arkansas and Mississippi.  As warmer air was pumped north across that snowpack it melted very quickly resulting in much more bare ground over the middle of the country in just 2 days.
