Good Thursday morning bloggers,
A small complex of thunderstorms tracked across central and southern Kansas early this morning and we had a few showers on the northeast edge of this complex. One shower made it all the way to the state line in Overland Park, and then a second heavier one created this beautiful sunrise rainbow at 6:10 AM. I awakened early today and didn't even know what day it was for a few seconds. Then, I looked outside and saw that it was raining very lightly at around 6 AM and it hit me that it was Thursday. I took this picture and then turned up the contrast so you could see the rainbow a bit better. You can see the rainshaft to the south and the rainbow just north of the heavier rain. The base of this shower was way up at around 10,000 feet up:

The weather pattern is wanting to set up into summer, but the LRC refuses to let go. This year's weather pattern continues to cycle and the last few weeks of this same weather pattern that set up last fall will be interesting to watch unfold. I do believe there will be at least a small heat wave sometime in the middle of the month, but it may be short lived if the pattern continues (go to www.LRCWeather.com and click on the blog over there for more details on what is in our near future). Let's discuss this holiday weekend forecast. Look at the surface forecast from the 00z GFS run valid on Saturday morning:

There are a few things to notice on the surface forecast map above. First of all the surface low is rather weak with a central pressure of 1011 mb (29.80" of mercury). The barometric pressure is a measure of the weight of the atmosphere above you at any given time. This weak surface low is a sure sign of summer. Hey, it is July for crying out loud but this same weather pattern continues to cycle and we have yet to really have summer settle in. The jet stream reaches its weakest and farthest north position by early August and then it will begin a very gradual change and shift south from later August into October and this is when the old LRC falls apart and the new one begins. Anyway, what does this mean for the holiday weekend. Look below at the rainfall forecast for tonight through Saturday:

A weak warm front will be forming over Kansas tonight into Friday. The next complex of thunderstorms is likely going to be a bit stronger than this mornings and right over our viewing area early Friday. Then, a third complex of thunderstorms should form Friday night into early Saturday, but this one should push the front south and we may have light north winds by Saturday allowing for a dry evening for fireworks. At least this is how it looks right now. We will be tracking these weather developments on NBC Action News in HD and preparing some special weather graphics for our weathercasts.
I am going to be broadcasting live from the new tennis venue downtown at 5 and 6 PM. Our national tennis team, the Explorers, has its debut match tonight starting at 7 PM. Come by, have some fun, and say hi. Grandstand seats are $25 ($15 for kids 3-12). Have a great day. Let us know if you have any questions.
