Scattered showers and isolated storms have developed across portions of the eastern missouri ozarks this afternoon as instability has increased and the cap has weakened with the heating of the day. This scattered activity will continue to develop and slowly move east this afternoon dissipating early this evening, mainly occurring east of highway 65. Deep layer SHEAR is weak with the upper level high over the region. Mlcape values of 1500-2500 j/kg are in place east of highway 65. This activity is/will continue to be pulse in nature. Precipitable water values are around 1.75-2" and storm motions are slow, so heavy downpours can be expected with these showers and storms but will be brief for any given location and very localized as this activity is not widespread. The severe risk is overall low but a strong storm or two with wind gusts up to 40 to 50 MPH could be possible, but lightning and heavy downpours will be the risk with most of the storms that are able to develop today.
Isolated pulse type showers and storms will once again be possible on thursday afternoon/early evening. Coverage should be less tomorrow than what is occurring today; therefore, most locations will likely remain dry on thursday.

The upper level ridge will remain over the area friday into the weekend before starting to flatten some later this week. Highs will continue to warm into the middle 90S to near 100 degrees again friday and saturday, and possible again on sunday, especially across the southern portions of the area. A slightly drier air mass will start to move into the area late week, so dew points may be slightly lower, but heat index values around 100 degrees are expected through at least saturday. A heat advisory is in effect for the entire area through 8 PM saturday.
An upper level trough will move south into the plains late this weekend then will move northeast into the great lakes region early next week. The trough will flatten the ridge some and send a front south into the area later saturday into sunday. Shower and storm chances (30-70%) will occur saturday evening into sunday with the best chances across the northern portions of the area closer to the upper level trough. With the upper level support remaining more to the north, rainfall amounts will likely decrease to the southeast and not all locations could be impacted by rain--especailly further south.
A cooler air mass will move into portions of the area late this weekend into early next week. Highs are expected to range from around 80 across the north portions of the area to around 90 across southern missouri early next week as the upper level trough and cooler temps remain north of the area.
