9:30 PM update:
Good evening bloggers. Tropical Storm Fay is about to move over the open water of the Atlantic Ocean and the water is very warm. Fay should become a hurricane, and then become stationary offshore before moving back to the west and do something a hurricane may have never done before.....track across Florida from the southwest to the northeast, stall, and then slam into the northeast Florida coast.
For us......this forecast is becoming like this entire month. It should rain with the pattern we are in. The latest NAM and NGM maybe, just maybe bring a few hundreths of an inch of rain. So, confidence is low. We will be going over all of this tonight after the Olympics.

Good morning bloggers,

Tropical Storm Fay tops the weather news today, and it could produce 12 inches of rain in Florida. A radar image from 9 AM this morning shows the well formed center of Fay which shows how conditions are so favorable for it to become a hurricane, but it is over land so unless she move back out to sea we will avoid any strengthening. While Fay is a major rain producer our attention shifts to the upper low that was in Canada last week, dropped south into Colorado over the weekend, and now it is moving into Oklahoma as you can see below:

The upper low is going to track north northeast and begin losing its identity as an upper low as it gets close to Kansas City. Before it loses its punch rain should spread across most of our viewing area. Look below at the forecast position of the upper low at 7 PM Wednesday:

Little disturbances rotating around the weakening upper low will combine with low level moisture surging in from the south tonight. Rain bands will develop and rotate around the upper low. We will likely see rain moving from southeast to northwest around the north side of the upper low. How much rain will fall? It could still be a challenge as we have a very dry August air-mass to overcome.
Rainfall amount forecast as of Tuesday morning:
- Trace or none: 1%
- .01" to 0.09": 20%
- 0.10" to .25": 80%
- 0.26" to .75": 50%
- 0.75" to 1.25": 30%
- More than 1.25": 5%
As the upper low lifts north into Kansas late Wednesday into Thursday it should bring a tropical air mass with it. Dewpoints should rise to 65 degrees or higher and provide the moisture necessary for some heavy downpours. But, will this moisture move in with the southeast flow at all levels? I think so! This forecast, above, means that we are expecting at least .10" to .25" of rain with a pretty good chance of up to 0.75". And, there is a 30% chance of over 0.75". And, there is a 99% chance we see measurable rain. This is what we think right now. We will update this with our thoughts on NBC Action News today at 5, 6, and 11 PM (after the Olympics).
Have a fantastic day!
