Weather Rewind, March 4-10, 2012
Last week's temperatures averaged out to 4.1 degrees above normal for this time of the year, much of that on the back of Thursday's 70 degree high in Philadelphia. The Wednesday through Friday (pre-dawn) warm wave provided daily average temperatures of eight, twenty, and eleven degrees above where they are supposed to be at this time of the year...and those pretty much balanced out the seasonably cooler than average rest of the week.
We picked up a trace of snow on Monday with some flurries and snow showers that moved through the region, with some locations on Thursday night into Friday morning picking up a few hundredths to a tenth of an inch of rain with the cool front passing through overnight. Outside of that, the week was rather dry from a rainfall perspective.
Nationally, the trend the first week plus of March has been much the same as winter has been -- mild to very warm for everyone east of the Rocky Mountains, with some degree of chill for the Rockies and West Coast. This trend will continue for the next ten days, probably amplified a bit more as a big ridge of high pressure sets up shop in the Ohio Valley and Southeast, with a sharp trough in the Southwestern US.
