Radar images show the 'squall line' as well as the rain showers that nicked the Cape over night.
Things are pretty much on track this Christmas morning as expected per yesterday's post. We got down to 68 degrees for a brief time last night, but for the most part it hung right at 70 degrees. A quick rain shower nicked the Cape area about 3 hours before sunrise and we got a quick 0.10" of rain in short order with winds gusting to an estimated 30mph. But those are now long gone as most of that activity is forming and remaining off shore. The tornado producing squall line of yesterday is still marching east and now about 75 miles west of the Florida west coast. In line with yesterday's thinking, still expect it to break up as the supporting low pressure area which created blizzard conditions from Texas to Oklahoma and into the Dakotas moves NNE and 'stretches' out all the associated energy with it. As the line of storms thins an upper and mid level jet streak approaches our area and spills debris cloud across the state by 8-9am which should remain in place the rest of the day. Chances of rain will increase despite the fact that the squall line will become non-existent south of a Daytona Beach - Gainesville line as there is a band of deeper moisture and a tad of instability being shoved this way. Yesterday I said our best chances of thunder would be between 1-4pm. I'm tempted to take out thunder and just make it our best chances of rain will be during that period.
Otherwise, the temperature forecast is still on track with a high today maybe a degree warmer than yesterday despite the cloud cover. Why? We lose the wind off the ocean as it will start to come out of the southwest and not off the 67 degree ocean water. Rain, if any, will end by midnight tonight...but not expecting more than 1/2" anywhere as even the heavier showers that manage to formulate will be moving briskly due to the aforementioned mid level jet streak.
Cooling air temperatures ensue tomorrow with a continued falling trend through Monday with lows right on the coast perhaps in the upper 40s Tuesday morning but otherwise in the mid 50s. Probably up to 10 degrees cooler inland though or perhaps just west of the Indian River. Still fearing abundant high cloud coverage after a period of good clearing immediately behind the front..so after a sunny Saturday we might be doing an about face to the pesky cirrostratus clouds. Still up in the air as to rain chances on Wednesday or late Tuesday...but as it looks now it's actually appearing to be more likely that this cold front will return as a warm front as yet another wave of low pressure forms along its remainders in the Gulf which will move ENE across the state and lift the boundary back toward us for a second blow...this time in the form of stratiform rain...blah's ville. But, that is still a big "if"...so I will continue to monitor this possibility. Perhaps when the later morning model runs have completed running we'll have a better idea of what is to come rain wise. Will reflect on this again in tomorrow's post.
