Weather Rewind: March 31-April 6, 2013
Temperatures over the past week were four degrees below average as started April on a cool note. That cool note reverses itself this week in a rather marked fashion. While we topped 60 on two occasions -- Monday's 66 the warmest day since late January -- we also dealt with a rather chilled 46 degree high in the wake of a frontal passage that moved through the region on Monday afternoon. Tuesday's 46 and Wednesday's 49 were the coolest highs on those particular dates in several years and more typical for early March than early April.
Rainfall was modest last week -- 0.27" for the whole week, two-thirds of it falling on Sunday with a disturbance moving through, the other third with a coastal low that moved through in the pre-dawn hours on Friday. The Shore picked up over an inch of rain from the coastal low on Friday morning but the northwest edge of rain cut off effectively along I-95.
Nationally, the same chilled pattern that dominated March ruled the first week of April -- coldest air to normal in the Northern Plains and Upper Midwest, with cool to chilly across the Ohio Valley southwest through the middle of the nation. Warmth ruled the western 40 percent of the country...but this all changes this week.
