(Images: Show the location of the front on radar quite impressively as it passes across Brevard County. The other image is what it looked like outside at the same time. And today is December 1st...read more about this date below:
1.The first day of the astronomical winter is December 21.
2. The first day of the climatological winter (as defined by the World Meteorological Organization) is December 1. That's today!
3. The first day of the ecological winter occurs locally with the end of the growing season. This date varies from one region to another and can shift from one year to the next; however in general, the ecological winter begins in November in cool temperate climates and December in mild temperate climates.
Well, as noted the cold front is moving on thru right now and will complete it's passage over Central Florida before noon time. Northwest winds behind the front will usher in much drier and cooler air during the course of the day with our high temperature of the day likely already reached around 7AM or 8AM this morning.
THIS AFTERNOON: Clouds will begin to clear after a post-frontal trough crosses the area which will produce another rounds of a light sprinkle and enhanced cloud cover chances, but this should be out of the picture by late in the afternoon. The main intolerable difference today will be a northwest wind harboring in a much cooler, modified Canadian Air Mass during the course of the afternoon and through the evening tonight.
TONIGHT: Clouds will have cleared by sunset, or close to it. Winds will stay elevated throughout the evening as temperatures fall to near 49F along the coast and near 45F inland.
THURSDAY-SATURDAY: Mainly clear skies will prevail throughout the period with a gradually waning wind strength from the NNW-N late in the period. Morning lows will probably bottom out on Friday morning where the correlation of lightest possible winds and cold air advection will make their greatest intersection across the meteorological realm of possibilities for this particular system. Lows in the low 50s near the coast and highs will struggle with 70 degrees.
SUNDAY: Very little change with regard to temperatures or sky cover, with a gradual warm up...but not by much. We are in it for the long haul. Another front will enter the picture next Tuesday or Wednesday to repeat this process all over again, and next time maybe even cooler to down right cold with its arrival. Looks like our days of 80 degrees are over outside of an errant "day before the front" event.
Perfect timing though, the first day of Meteorological Winter.
