Taney County work week 4 including the Fourth of July!


Showers and isolated thunderstorms could linger into Monday due to a mid level front that becomes established across southern Missouri. Computer model runs, however, don't generate much instability, therefore, severe storms are not expected.

From Tuesday through Thursday night, other than an outside shot of a shower or thunderstorm, mainly warm and dry conditions are expected through the mid week period. Look for the mercury to climb back towards the upper eighty degree mark!

As the work week goes on a weak zonal front will evolve, and eventually re-positions to the southwest toward the weekend. Not only will temperatures warm a few degrees, shower and thunderstorm chances increase.


As a matter of fact, medium range models bring a complex of storms through southern Missouri Friday night into Saturday morning. Heavy rain will be a possibility, along with a potential severe risk. Shear will be modest, although instability will be sufficient for organized storms as moisture depth increases.

The fourth of July weekend will have the potential for being somewhat active across southern Missouri. Anyone that has plans for participating in outdoor activities should closely monitor later forecasts regarding potential thunderstorm activity for that weekend.

Taney County Work week three in June!


A cooler air mass will spread into the area Monday behind the front that went through on Sunday. Highs will warm into the upper 70's to the lower 80's on Monday with lows in the upper 50s to lower 60's occurring during the evening hours.


Warmer conditions will then return Tuesday through the rest of the week as highs in the upper 80's to lower 90's occur each afternoon.


The warming trend will linger into Wednesday as highs reach the upper 80's to low 90's and heat index values warm into the low to mid 90s. Not expecting much in the way of rain chances until about the Thursday time frame.


Heading into Thursday, PW (Precipitable Water) values of 1.5 to around 2.0 inches will be possible along and south of the Interstate 44 corridor, with the higher amounts across south central MO. It looks as if models are keeping the track slightly further to the southeast of the area than last nights model runs. Our thunderstorm chances start on Thursday, but will mainly be over the eastern Ozarks initially as energy from around the tropical system moves into Arkansas and south central MO.


On Friday, a southward moving front will push into the area and offer the best chance at showers and thunderstorms, with the tropical low pushing into the boot heel and quickly into the TN valley. Precipitation may shut off pretty quickly on Friday evening in the wake of the low and front.

Models are showing some differences heading into the weekend. GFS wants to keep things dry behind the front, while ECMWF brings another wave of energy and precipitation into the area Saturday night into Sunday. Will keep the low end pops going through the weekend.
Going with cooler than normal temperatures from the weekend into the early part of next week behind the front with a cooler air mass moving into the region.

Precipitable Water - A measure of the depth of liquid water at the surface that would result after precipitating all of the water vapor in a vertical column over a given location, usually extending from the surface to 300 mb.

June week 2ish weather for Taney County!


Monday will be even warmer as 850mb temps rise to 20C. Most locations along and north of I-44 will reach 90 with a few low 90s possible. With 700mb temps between 10-14C, it will be hard to get
precip, none the less clouds. The exception will be across far south central Missouri (Oregon county) where an isolated shower or storm is possible since the cap will be a tad weaker there.


A strong upper level trough will move into the Northern Plains Tuesday with a trailing front into Kansas and Oklahoma. Areas across the eastern Ozarks may see an afternoon shower or storm however confidence is not high in this given warm mid level temps and little forcing available. With 850mb temps around 20-21C, expect highs around 90 again. Showers and storms will fire in KS and OK Tues evening as shortwave energy approaches. Most or all of this activity will stay west of the area given increasing convective inhibition during the Overnight hours.


Frontal boundary pushes closer Wednesday afternoon and this may be our best shot at showers and storms given that the air mass will likely be pretty unstable. Wind shear looks less than 30kts however instability will be high therefore will need to monitor for stronger storms Wednesday afternoon and evening. Wednesday also looks warm with highs around either side of 90.


Frontal boundary then looks to become diffuse or go stationary across the area from Thursday into the early part of the weekend. A zonal mid level pattern will exist during this time. This signal would suggest several chances for showers and storms during this time frame. Otherwise temps look to remain in the mid to upper 80s.

Heat index values this week will likely reach the middle to potentially upper 90s across portions of the area with the areas north and west of Interstate 44 into the Osage Plains favored. While this is not uncommon by any means, it will be the warmest it has "felt" so far this calendar year.

June work week one for Taney County!


It was beginning to feel a bit like summer, over the weekend, what with the lazy clouds and pop up shower chances. That trend will continue through Sunday, June the 4th and on into the coming work week.... a pretty boring stretch weather wise!


Most of the area should stay dry on Monday, though a couple of showers/storms are possible through early afternoon across the Missouri/Arkansas state line. Cloud cover will clear as the day goes on, with lower dew points building into the area by afternoon and evening.


Tuesday and Wednesday continue to look like very nice days, with highs both days in the upper 70s to around 80, and lows in the 50s.


Upper ridging will begin to build back into the area Thursday into the weekend. There will be chance for thunderstorms late in the workweek as a couple of shortwaves move through the area, though
the overall setup doesn't look terribly impressive. Temperatures look to return to the mid 80s by the end of the workweek into next weekend.
