AVIATION. High pressure will keep rain chances lower in west Arkansas and more scattered thunderstorms in the east. Best rain chances will be this afternoon and evening. VFR conditions are expected.
PREV DISCUSSION. (ISSUED 358 AM CDT Sat Jun 12 2021) SHORT TERM . Today Through Sunday Night The upper level high pressure system centered over west Texas will remain there through the weekend. This high will provide a northwest flow aloft for Arkansas today and north flow on Saturday.
This pattern is indicative of nighttime MCSs. One MCS made it into northeast Arkansas overnight but quickly dissipated. A larger system went southward into Oklahoma.
A cold front will move into Arkansas this afternoon and stall in central Arkansas Sunday. Showers and thunderstorms are expected to develop along or near this front this afternoon. Should an MCS develop tonight it would move south along this front. As a result, rain chances will continue today and tonight and again on Sunday. Humidity levels will be high and heat indices today and Sunday will be around 100 degrees to 105 degrees.
Highs today will be in the lower 90s and Sunday will be in the upper 80s to lower 90s. Lows tonight will be in the lower to mid 70s and in the mid 60s to mid 70s Sunday night.
LONG TERM . Monday Through Saturday A benign synoptic-scale weather pattern will take shape this upcoming work week characterized by with broad ridging over the Srn Rockies and a flattening trough moving off the Ern coast. Additionally, a quick moving trough will swing across the Great Lakes region on Tuesday. Between these features, NWrly flow will be established through much of the week. While active weather does not appear likely in the foreseeable future, sneaky NW flow regimes can harbor the development of MCS complexes with little model reflection, which in turn would move through the mean flow and towards the Natural State. This NWrly flow pattern will be monitored closely through the week.
Late in the period, there is some indications that the ridge over the Rockies will flatten, and with this subtle weakening, a new trough may swing across the nations mid-section, with a surface boundary in tow. Both long range forecast model suites suggest this is a possibility but it becomes more complicated than this once eyes turn towards the tropics. There is some indications that a tropical system, of unknown strength, could be present over the Wrn Gulf towards the end of the work week. The aforementioned surface cold front and approaching tropical moisture will likely result in decent rainfall across the Srn CONUS, however this falls outside of the long range time range.
At the surface, high pressure will approach from the N and E early in the week. This will serve to push a weak boundary across Nrn portions of the state, at least reducing dew points a few degrees across the Nrn half of the state. A re-enforcing surge of cooler air will be noted in the wake of Tuesdays upper trough passage. Lower dew points will advect further into Cntrl and even Srn portions of the state for a couple of days. By Thursday, low level flow will switch back to the S/SW with warmer and more humid air filtering back into the region. This will occur along and ahead of a developing cold front over the plains states. PoPs will not quite return in time to mention at this point, but will likely increase heading into the weekend.
Overall, dry weather can be expected which will help dry soils over Srn and Ern portions of the state. Temperatures will be on par with with typical averages, lows in the 60s to near 70 and highs in the upper 80s to lower 90s. Heat index values should mostly stay below the century mark.
