The slow cool-down this week will accelerate mightily over the weekend, as the Tampa Bay area should brace for what perhaps will be the last cold blast of the season.
Extra clouds streaming in from the Gulf of Mexico, and northerly winds will help keep today's temperatures in the low-60s, Storm Team 8 meteorologist Leigh Spann said.
The below-average temperatures will continue tonight as lows will drop into the mid-40s, before another cold front brings a 20 percent chance of rain Saturday with highs struggling to reach the low-60s and lows in the low-40s.
But the real winter chill comes on Sunday.
Temperatures will plummet as a mix of sun and clouds, along with some drizzle, will keep Sunday's highs in the mid-50s.
"For March to start out in the 50s is almost unheard of," Spann said.
Lows on Sunday night will drop to near 40 in Tampa, and into the 30s in Pasco County and northern areas, before a gradual warming trends starts Monday with highs climbing to the mid- to upper-60s to start the work week.
