A winter weather weekend, now a spring-like week
The snow, sleet, and freezing rain/drizzle over the weekend provided ample proof that it is January in the ‘Burg, but today (Monday) we revert back to the above normal temperatures that we’ve become familiar with most of this winter. The fog this morning is due to warmer air flowing in from the southwest finally beginning to counter the dreary cold air damming (CAD) wedge that’s been parked over us for several days. As this air cools from contact with the remnant ice and snow on the ground the moisture condenses and forms fog. This should disperse by noon as rainfall ahead of and along an approaching cold front pushes into the area, which should finally scour out the low level cold air of the annoyingly persistent CAD wedge and push our temperatures into the mid-40′s (F) today.
This front and its associated dynamics are what caused a spate of tornadoes over the mid-South last night and may spawn a few more today, but we won’t see any of that severe weather. However mark March 20th on your calendars for the statewide tornado drill for your home, business, or school. Strong tornadoes can and do occur in the Old Dominion!
The air behind this next front is of Pacific origin – vice Canadian – so it will be relatively mild and springlike with highs Tuesday and Wednesday reaching the low and mid-50′s. Then another surface low pressure system will organize over the southern Plains and drive our way Thursday into Friday with more rain. Behind it temperatures will cool off again for next weekend but at the moment I don’t see any indications of major Arctic air outbreaks for at least another 7-10 days. Happy Monday!
