Mother Nature seems not to have noticed that today is the start of meteorological spring! With a wintry mix making for a day of hazardous icing, March is sticking with winter - and tradition - by coming in like a lion. The previous WINTER WEATHER ADVISORY has been upgraded to a WINTER STORM WARNING for DC, its close-in suburbs, and counties north and west through 3 AM Monday. With plenty of moisture streaming north and cold air at the surface, look for a mixture of sleet and freezing rain for the rest of the day. The precipitation is expected to end as freezing drizzle toward sunset. Total accumulation for the immediate DC area should be an inch or less. The potential for roads coated with ice will make for hazardous driving- and walking- conditions throughout the day. Temperatures will gradually rise to the lower 30s. Traveling both north and west today will be especially challenging since those areas could see significantly more ice; a WINTER STORM WARNING is in effect for the Baltimore metro region and northeastern Maryland. Look for a partly cloudy start to the new week with highs tomorrow in the low 40s. NOTE: February ended much as it began with readings well below normal. In fact 16 of the last 17 days were below average with only 6 days close to where they should have been the entire month. Look to thaw out on this coming Wednesday when highs in the mid 50s will be much appreciated!
