Battle of Fredericksburg reenactment to be cloudy, mild, and even damp
Big things are happening in the ‘Burg this weekend with the 150th anniversary of the December 1862 Battle of Fredericksburg, but lest we forget today – December 7th – is also Pearl Harbor Day. The weather will generally cooperate with festivity preparations today (Friday) even though this morning a few showers pushed through the area as a result of the surface high pressure moving off the coast and ushering in southerly winds. The moister southern air rode up and over the cooler dryer air at the surface – a process called isentropic lift - and a wee bit of rain resulted that barely registered on local rain gauges. The rest of Friday will be mild but cloudy with a high temperature in the mid-50′s (F).
Saturday we’ll see more clouds after a potentially foggy start but there is at least a chance at the sun peeking through at times. The festivities should remain dry ahead of another front approaching the region, and southwesterly winds will boost temperatures even further as the tomorrow’s highs climb into the upper 60′s. Thus event-goers should be able to get by with a light jacket / windbreaker.
Sunday however will be a different story as a “backdoor front” slides south of the ‘Burg as shown below in this forecast graphic for 7 a.m. that morning:
The winds north of this front will turn northeasterly and bring cool damp air over the ‘Burg along with a low overcast. This cold air damming wedge will hold Sunday’s temperatures down to the upper 50′s and will also bring some light rain or drizzle that will only total to another few hundredths of an inch. So Sunday’s festivities may require adding an umbrella or a raincoat to the ensemble in order to stay comfortable. (One note: should there be any simulated musketry or artillery firing on Sunday the low overcast could render things a bit louder than normal.)
Then, the first part of next week will bring a strong cold front from the west that will scour out the surface wedge and provide some more rain before opening the gates to some more seasonal air. Temperatures through the middle of next week will top out near the 50 degree mark.
Enjoy this weekend’s actitivies as you get your history geek on!
