THE ACTIVE (AND RATHER WET) PATTERN CONTINUES THIS UPCOMING WEEK… IS THE PATTERN A RESULT OF EL NINO?… MILDER TEMPERATURES ARE EXPECTED BY MID-WEEK

The weather pattern this week will be very active as we see another system that should bring us rain by mid-week. Another system may bring us precipitation by next weekend. The system that affected us on Saturday brought about three quarters of an inch of rain┬áto my neighborhood. Snow fell in northern and western Virginia which was the first winter weather event of the 2009/2010 season. Amounts weren’t excessive but were enough to cause some travel problems. The Northeastern states were also affected. That system is gone and high pressure will bring us a sunny but cold Sunday. A weak system may bring us a shower on Monday but a much stronger system may bring us showers and even thunderstorms by Wednesday. This next system may bring a major blizzard to parts of the Northern Plains states and severe weather to parts of the South. The low pressure system is expected to become quite strong as it moves towards the Great Lakes. Later in the week, another system may bring some precipitation to Hampton Roads…. As I stated in an earlier post, November was the wettest November in recorded history at ORF and December seems to be shaping up to be a very wet month. Why has the weather pattern been so active? Well, it is a combination of many global factors but the major player seems to be the El Nino, or the warming of the Eastern Pacific Ocean. I’ve seen statements that this is not the typical El Nino, but nonetheless, it is causing our precipitation totals to be quite impressive. Since early August, we’ve been running above normal for the most part and we will probably see a continuation of the active pattern as we head through the winter season. Maybe that will mean some snow for us here in Hampton Roads. We are VERY overdue for snow since our last significant snowfall was in December 2004.
