Frost could be widespread by Wednesday morningPosted Apr14, 2008 at 10:16 PMIt's been a little too warm for snow except in the higher elevations around Southwest Virginia ... we've just had chilly sprinkles with temperatures in the 40s in the Roanoke Valley. The real issue could be how much frost develops by Wednesday morning across the area. There could be some frost on Tuesday morning if the cloud blanket rolls away overnight, allowing radiational cooling to take temperatures near freezing. Tuesday night into Wednesday, however, clear skies and calm winds may take temperatures below freezing across almost all of the area, and this could allow for a widespread frost. A frost advisory is in effect for Tuesday morning and a freeze watch is in effect for Wednesday morning, which may be upgraded to a freeze warning sometime Tuesday. Though Thursday morning could be pretty cold, a warmup is expected to set in Thursday afternoon into Friday. One can never be totally certain, but there is a good chance this will be our last bout of near freezing weather this season. |

TQ : →http://newxsfc.blogspot.comThere/s also cause to beware frost when MIN TEMPS in the M/U30s are expected b/c these readings...observed @ shelter height (~5.5' AGL)...can be as much as 5°F greater than ground level temps.

JulieHi, Kevin; We had some pretty snow showers last night and I definitely saw the white tinge to the higher elevations this morning. Even though the growing season has not officially started up our way, many trees (especially fruits & ornamentals) have started to blossom. But the sub-freezing temps last few days have not caused serious damage; they haven't lasted long and daytime temps have rebounded nicely, keeping the soil/ground above freezing. Temps again progged to be around 26 tonight; cold-hardy plants in the garden are all OK so far as they are close to the ground and seem to be fairing well. Could sure use some more rain, though!!

I'm a big fan, you write clearly and cogently on the weather, and even admit when you get it wrong.
I thought you might be interested in this website on the correlation between sunspots and climate (and other stuff).
