For those who have been cursing the lingering cold air in the Baltimore area, a reprieve is in the forecast before the weekend passes.
Temperatures are expected to rise consistently above normal for the first time in a month come Sunday. The National Weather Service is forecasting highs in the lower 60s on Sunday, rising to the upper 60s by Monday.
Climate forecasters see it as a strong pattern change. While cold air had been rushing across the eastern U.S. at the end of March into early April, a warming is predicted east of the Mississippi River over the next two weeks.
The Climate Prediction Center in College Park forecasts at least 40 percent odds that temperatures will rise above normal across the eastern half of the country. A chill is meanwhile expected across the Rocky Mountain states.
Normal highs this time of year in Baltimore is about 60 degrees, rising quickly to 70 degrees by the end of the Month.
Meteorological spring has been chilly so far, particularly relative to spring 2012. Last month's average temperature of 40.6 degrees at Baltimore-Washington International Thurgood Marshall Airport was 2 degrees colder than December's average, even.
March 2013 was about 12 degrees colder than March 2012, on average.
