What an absolutely beautiful afternoon out there. Highs today have been in the 75-80 range and should be mild again tomorrow, although not as mild due to an increase in clouds in the PM hours especially.

A rather dynamic storm is going to organize in the middle part of the country over the next 24-48 hours. The energy for this storm is just now coming into the western part of the country. It really doesn't look like much now actually. Again this will be changing quite a bit over the next 24 hours.

The surface reflection of this energy will really crank up tomorrow. It'll eventually turn into a 995 mb (29.35") or less surface low in Central KS. So for those who "Feel" the effects of pressure changes tomorrow may not be the greatest day for you. As this system cranks up and spins away in the Plains, anotehr impressive dry line will be created to our west and move towards the region. Dewpoints here should increase, although not get out of hand. Right now the moisture, while there, isn't overly impressive towards the southern Gulf Coastal area until you get right to the coastline, but now the flow is off the Gulf of Mexico, so the moisture will start streaming through TX over the next 12 hours. Here is the 1PM surface map showing the moisture well south into TX...


This moisture will be surging northwards tomorrow, and eventually we'll start to see at least 50+ dewpoints move in. The moisture may be a bit more impressive (at the surface at least) to the west of here. From Emporia to Wichita to Concordia, dewpoints should get to near or above 60. With such a dynamic and strengthening storm system, T/Storms should rapidly fire up along and ahead of the dry line that will be pressing eastwards. The storms, because the system is so strong should move to the N/NNE initially as the whole squall line comes together and presses to the east as well. The higher risk, per SPC of severe weather is to the S/SW of the KC region. I can't rule out some hail/wind here tomorrow evening/night however since the storms will be mature as they move into our area. There is also the potential for a fast shot of some heavy rainfall with the storms as the whole line moves through the region. Here is the latest forecast from the SPC...really no different than what we showed you earlier today.


This storm aloft will form into an upper level LOW that should pass right on top or close by to KC on Friday. This means 1) a lot of gray skies 2) off/on chilly showers that will be rotating around the storm 3) the showers may not affect all 4) colder air will spill in with blustery NW winds behind the storm system on Friday night. What's interesting, and perhaps off the radar for some meteorologists, is the potential for even some funnel clouds in Central or Eastern MO on FRI called Cold Air Funnels. this will depend on whether or not the storm ingests dry air into it's circulation, allowing sunshine to break out from the Lakes eastward on FRI...but that too could be an interesting weather day for the Show Me State.

The air behind the storm will be chilly for about 12-24 hours, until the storm pulls away SAT @ Noon or so...then things will moderate and highs should bounce back to the lower 60s on SAT and near 75 on SUN.

Next week will be rainy at times again with up and down temperatures.

Hey before I leave you...I thought this was kind of cool...take a look!
