More changes, more of the same

Have you ever heard the saying that “The more things change the more they stay the same”? That pretty much sums up this week’s weather for Fredericksburg and vicinity. Our long-standing pattern of quick shots of cold air followed by quick warmups followed by more cold air will continue for the foreseeable future.

Today – Monday – will wind up 12-13 degrees above normal as temperatures rise into the upper 50s. Sunshine will reign during the first part of the day but cloud cover will increase this afternoon. Another cold frontal approach will pump moisture northward ahead of it and the result will be some light rainfall tonight and early Tuesday. This will be an all liquid event as the minimum temperature Tuesday morning will only drop into the lower 40s.

The sun looks to pop back out Tuesday afternoon and temperatures will once again be in the 50s as this latest cold front ushers in mild air of Pacific origin rather than the Arctic stuff. This forecast map illustrates the situation at 7 p.m. Tuesday:98fndfd_init_2014011300Note the second cold front over the Midwest trailing the first one I just described. It is actually the leading edge of a large scale atmospheric “trough” and will open the door to more cold air out of Canada (but not the frigid stuff we saw last week). Thus the ‘Burg will see typical January temperatures the last half of this week.

As this next installment of colder air interacts with some leftover moisture the ‘Burg could see some flakes Wednesday night into early Thursday morning. At the moment it doesn’t appear to be a big deal but we’ll keep an eye on that anyway.  Meanwhile enjoy the brief interlude of warmth!
