Is this really happening? Yes, it's a dream and so far a good dream! Just what the lawn doctor needed! Yet another storm system taking aim on the central and southern plain states. I call this pattern "Cut Off Low Weatherman's Woe". As you can see the upper level weather pattern 72 hours from now showing a storm system over the rockies with lots of circles around it. That's an indication the storm is cut off from the main jet stream flow running west to east across the northern sections of the country. With very weak steering currents this far south the upper low will more or less sit and spin as it slowly wobbles east until the northern branch of the jet stream finally drops south and kicks it along faster to the east early next week. So over the next few days the exact track of the upper low is very uncertain and tough to forecast. Thus the phrase "Cut Off Low Weatherman's Woe". Get it?
The good news is that the southern plains and Oklahoma is on the wet side of the system for several days before is shoves east. This means more significant rain chances as we head into the weekend! Expect chances for showers and thunderstorms to go up again Thursday through at least Sunday depending on the exact track and speed of the storm system. Locally heavy rainfall the main threat but can't rule out some severe weather as the system moves closer. The instability may be somewhat limited but lots of spin in the atmosphere could mean the threat for severe weather and even tornadoes if things set up a certain way. Hopefully just more rain but stay tuned!
Here's the past 5 day rainfall totals from the fine folks over at the Oklahoma Mesonet. You can see a good chunk of Oklahoma getting significant rainfall with that last system. I had my doubts but was proved wrong. Now we need more!
Looking into the future here's the rainfall forecast through Sunday morning. This computer model is showing more widespread rainfall throughout the central and southern plains starting Thursday and lasting through the weekend. After this system moves east of Oklahoma early next week the pattern remains active with more rain and thunder in the forecast middle parts of next week. Sounds too good to be true but maybe, just maybe things are changing.
