Record Warmth, Then Winter's COLD

Get ready for a dramatic roller-coaster ride this weekend as temperatures soar to near record levels followed by a dramatic dip to start the week.  So if you're out shopping this weekend, you might look for sweaters while you're probably wearing shorts and flip-flops.  Southerly winds returned today nudging the mercury into the upper 70s and like last weekend, we'll challenge records.  Saturday's record of 83° looks safe, but Sunday's 82° could be either tied or eclipsed.  After that, a cold front sweeps in releasing a pool of arctic air that's finally making a move after building in Western Canada all week.

As the front moves in late Sunday, showers could develop ahead of it.  I'm not expecting strong thunderstorms, but there could be some decent downpours late that evening into the pre-dawn hours Monday.  Here's a depiction from a long-range computer model.  The green represents rain moving across Southeast Texas after midnight Sunday going into early Monday morning:

The graph at the top of the blog shows the expected high temperatures the next four days, but you'll also notice how cold it will be in the morning.  We could see our first freeze Tuesday morning with several more to follow through Thursday morning.  Get ready for it!
TONIGHT: Partly cloudy skies early, then becoming mostly cloudy with areas of dense fog before sunrise. Lows in the low to mid 60s with light southeast winds 2-5 mph.
SATURDAY: Low clouds and morning fog with some light misty rain, especially east of town. Then skies become partly cloudy by afternoon with a stray spotty shower. Highs in the low 80s with breezy southeast winds 10-15 mph.
SUNDAY: Areas of dense morning fog, then partly to mostly cloudy skies with occasional showers.  Showers and thunderstorms developing late in the evening. Highs in the low to mid 80s before the rain. Southerly winds 10-15 mph.
MONDAY: Morning showers exit off the coast. Skies gradually clear out. Windy and much colder. Highs in the mid 50s, northwest winds 15-20 mph.
