The Glow Likely to be No Show...

The glow we call the Sun was shining for a good part of this afternoon, but don't get use to it.  As mentioned yesterday, the upper SW flow is going to bring back clouds & showers for the next 5-6 days finally clearing out by Thursday & Friday of next week.   Watching the local weather programs this evening showed how lucky (or unlucky) some folks were regarding yesterday's training T-Storms.  While my house had barely an inch (1.03"), 20 miles to my west in Destrehan Capt. Hylton received almost 9"!   It was even worse up on the North Shore in Washington Parish where some folks got 15-20" while 5-10 miles either side of the training track there was less than an inch.   Look for the weak frontal boundary to start returning northward out of the Gulf on Saturday with clouds and a few showers.  Sunday will be warmer with some passing showers before the next big heavy rain threat arrives for Sunday night into Monday.   But there's more (Lee Zurik) as the next front will also stall awaiting yet another upper disturbance on Wednesday that could bring more heavy rain.  Finally, the SW upper flow will become westerly drying us out for next Thursday & Friday and cooling us down.   Some really cold air (30-35 below) sits over Hudson Bay with the below zero temps now down as far south as Minneapolis.   Omaha is only 10 with Dallas 43, but the SW upper flow will not allow that chill to march down to us.   It will take a flipping of the upper flow, currently a deep trough over the Rockies, with the deep trough forming over the Great lakes and East Coast for us to get real cold.  Right now, I don't see that happening for the next 10-14 days.  For those of you going out for New Year's Eve, it appears most of the rain will be gone before 6 PM with cooler & drier air allowing the fireworks to fly bringing in the New Year.  Stay tuned!
