Area Forecast Discussion National Weather Service Lubbock TX 1004 AM CDT Mon Jun 28 2021 .UPDATE... Based on current trends and expected evolution of shower activity, have issued a Flash Flood Watch for the Rolling Plains through this evening. Current shower activity appears to be propagating north-northeastward along a weak instability gradient, enhanced by the presence of a weak upper level cyclonic impulse currently over southern New Mexico. Overall bulk shear remains weak, but the weak veering wind profiles combined with an expected increase in instability due to modest surface heating across the Rolling Plains suggest that the development of additional convective cores within shower activity is plausible. While overall coverage of heavy rain is uncertain, rainfall rates within the heaviest activity this morning have been up to 2 inches per hour. With higher rainfall totals east of I-27 throughout the past few days, the flash flood threat is amplified this afternoon across the Rolling Plains. Elsewhere, areas of showers and a few pop-up thunderstorms remain possible across the entire CWA. /DWK && .PREV DISCUSSION... /issued 620 AM CDT Mon Jun 28 2021/ AVIATION... Light rain shower activity and possibly a rumble of thunder will continue for much of today at all TAF sites. Patchy low CIGS this morning are expected to mostly be MVFR to VFR but may drop into IFR category within heavier rain showers. Rain showers may then continue through the overnight hours with greater chances of widespread low CIGS moving in to all TAF sites. PREV DISCUSSION... /issued 247 AM CDT Mon Jun 28 2021/ SHORT TERM... Scattered showers and isolated thunderstorms will continue today within a very moist and cool environment. An upper level jet on the downwind side of an upper trough axis will continue to provide a broad area of upper level divergence overhead. However, we will begin to undergo rising heights overhead as an upper ridge over the eastern CONUS expands from east to west. Rain shower and isolated thunderstorm activity today and tonight will primarily be driven by isentropic upglide/warm air advection processes. So, updrafts are generally expected to be fairly weak. This is further supported by the thermodynamic profiles which remain similar to Sunday. The entire atmospheric column will be nearly saturated leading to moist adiabatic lapse rates. As a result, weak instability values will exist in this environment. Precipitable water values will persist around 125-150 percent of normal for this time of year. Because of these expected conditions, chances of severe storms will be zero to nearly zero. There will be a higher chance of heavy rainfall. But any convective development will likely be disorganized and heavy rainfall will not be destined for a long period of time in any one spot. Rainfall this morning under the heaviest cores have been on the order of only about 1-1.5 inches per hour at the highest. This rainfall/isolated thunder activity will continue through the overnight hours as moist isentropic upglide persists. LONG TERM... The upper-level trough that has brought upper-level support for precipitation over the region will begin to lift north on Tuesday. As the trough lifts, an upper high to our east will expand west over the region. This will effectively shut off much of the upper-level support that the area has had the last few days. At the surface, winds will become easterly on Tuesday as a surface high moves to our north. Winds will become southerly on Wednesday as a surface high strengthens over the southeastern CONUS. This will help lock in and reinforce moisture in the region. Precipitable water values are expected to remain ~150% of normal through the week as well. There is some chance that ridging will hamper daytime convection over the area. However, nighttime convection will still be possible and could aid in daytime convection if boundaries remain over or near the region. An upper-low will move over the Great Lakes region late this week, potentially driving a front through the region. This front will provide our next shot of widespread convection. As the trough deepens to our northeast, flow overhead will become northwesterly. This flow regime should allow for additional rounds of precipitation each evening as convection slides into the region from the higher terrain of New Mexico.
