Winter Weather Update- Sun PM
The NAM model has come in line with the GFS model for an all rain event for Monday night into Tuesday. This is more than fine, since we've had more than enough snow!
A large low pressure system winds up along the NE coastline Thursday into Friday, bringing very cold temps to our area and areas south. Right now, it looks like the low will be too far north to bring us much in the way of snow, but stay tuned.

Solar Climate Discussion (Updated 2/6): This past July and August (see post) (see post), I suggested that this winter would be unusually cold due to a prolonged lull in solar activity. The sun is beginning to come out of a solar minimum, and there has finally been the long expected increase in solar activity signaling the real beginning of Solar Cycle 24. There are several sunspot areas, but the solar flux still hasn't taken off. It's still early in the cycle. Total Solar Irradiance continues to be about 1 watt/m2 lower than it was during the peak of the last solar cycle, Solar Cycle 23, in April 2000.
As of early February, it looks like the solar cycle is providing the predicted colder than normal temperatures and the El Nino is providing the potent moisture rich southern jet stream. Continue to expect colder than normal temperatures into the spring.
