Not much change in the short term period will be seen. We will be on the periphery of the subtropical ridge to our east and a deepening trough to our west. SW flow aloft will setup in between. A cold front will make it as far south as the Ozarks of Missouri before lifting north again. This may be close enough to set off a few showers or isolated thunderstorms across the north and have gone with low end pops to account for this feature. The front will retreat as the high strengthens yet again leaving us hot and dry for the rest of the period. There could be and isolated shower on Saturday but generally dry conditions should be seen.
Period begins with subtropical ridge parked on the east coast and a trough with associated frontal boundary to the west. This keep the front at bay and prevent it from moving into Arkansas for now. Early in this period, the ridge should contract somewhat, allowing for disturbances to ride the SW flow aloft with around the periphery of the high. This will yield enough moisture with both the Gulf and Pacific open for business to bring in scattered showers and thunderstorms. With the timing of these systems hard to pinpoint this far out, have left low end pops to account for them and will increase once area and timing are locked down.
Beyond Monday night, things are rather...sketchy. There is still considerable disagreement among guidance in regard to a progressive ( ridge breaking down) or amplified ( ridge blocks front) pattern. Eventually though, the front will begin to move into the state as the high moves eastward or breaks down. Timing that is difficult this far out and the ridge thus far has won out each time. Have gone with a middle ground approach for the end of the period with the high slowly giving way to the front with time. I have left pops in the lower end of the spectrum for now as timing the front is still very mch low confidence at this time. But eventually the front will win out and breakdown the high, and there is some indication of that happening just beyond the period albeit it is a wait and see.
Good thing is that with increased cloud cover and decreasing sun angle, temps won't be near as bad as they are. Still above average but much more manageable even with the humidity.
