SHORT TERM. (This evening through Wednesday night) Issued at 341 PM CDT Tue Sep 29 2020

Near-term concerns revolve around continuing elevated to critical fire weather conditions. Strong northwest winds have developed across western Nebraska behind a weak surface trough that continues to track to the southeast. This has allowed sufficient and deep mixing of the boundary layer which has tapped into stronger mid- level flow allowing for momentum transfer gusts of up to 25 to 30 mph across much of the area. With the loss of daytime heating, we will see the boundary layer stabilize and these gusts to diminish heading into the evening. Have elected to leave the Red Flag Warning unchanged given the sporadic nature of the wind gusts and the driest plume of air being situated across the southern Panhandle into southwest Nebraska. Expecting mostly clear skies this evening through much of the overnight but given veering winds thinking Wednesday morning lows will remain more mild, only falling into the low 40s for most and upper 30s for some across the western Sandhills. A surface cool front will move into the area early Wednesday morning bringing with it another surge of dry air and heralding the start of a brief cooldown across the area. No precipitation is expected with this frontal passage but another day of efficient boundary layer mixing coincident with another strong mid-level belt of strong winds will make for more windy conditions across much of the area. With temperatures at h85 expected to be roughly 6 to 8 degrees cooler, will see daytime highs not climb as much as Tuesday with values ranging from the mid-60s along the South Dakota border to the mid-70s for areas south of the Platte River system. Winds at h7 will be pushing 40 to 50 knots which should yield gusts of 30 to 40 mph, the strongest of which are expected to occur north of Highway 2. Though temperatures will generally be below normal, dew points falling into the low 20s will allow for humidity values to again fall to around 20 percent across portions of the Sandhills and north central Nebraska leading to more elevated fire weather conditions. Humidity values remaining above critical levels preclude any headlines for the moment. Winds will decrease through the late afternoon as surface high pressure approaches from the north. Though yet to fully move overhead Wednesday night, expect a cold night as conditions will be favorable for strong radiational cooling. Expect lows to fall into the 30s with isolated pockets of upper 20s possible across the Sandhills. Frost headlines may be necessary for Thursday morning but will defer to later forecasts to address this.

LONG TERM. (Thursday through Tuesday) Issued at 341 PM CDT Tue Sep 29 2020

Beginning 12z Thursday. Following the passage of the cool front on Wednesday, the area will be squarely under the influence of the invading Canadian airmass. This will set us up for the coolest day of the week as high pressure noses in. Though skies will generally be clear, daytime highs are expected to hover in the 50s and 60s across the area thanks in part to h85 temperatures generally around 0-2 degrees C. Winds may be breezy early in the day as pressure rises approach 1 hPa/hr. This pressure gradient relaxes by the late afternoon suggesting wind potential will be maximized early in the day. High pressure will settle in the vicinity of Iowa Friday morning which should lead to the coldest morning of the forecast period. With dry air in place and winds becoming light, temperatures should manage to fall to the freezing mark and potentially into the upper 20s for some locations. Will need to consider Frost/Freeze headlines for Friday morning should this signal continue. High pressure slides to the east during the day Friday with generally southerly return flow overspreading the local area. This will allow temperatures to moderate some with a mix of 60s and low 70s for Friday. Another weak cool front associated with a developing surface low will bring a reinforcing shot of cooler air for Saturday, knocking daytime temperatures back into the 50s and 60s for the area. Some uncertainty exists with respect to precipitation chances associated with this weak system. While the GFS is dry, the ECMWF advertises widespread light rainfall across the area but particularly for areas east of the CWA. Thinking confidence is too low to add PoPs to the forecast at this range given forcing largely tied to mid-level vorticity advection and relatively dry air in the h7 to h5 layer. A second high pressure system will skirt the area to the east on Sunday leading to range of temperatures from the upper 50s in the east to low 70s across the Nebraska Panhandle.

Temperatures begin to climb back to above normal temperatures by Monday as ridging across the west begins to build into the central and southern Plains. This will keep any additional Canadian airmass east of the local area and put us squarely in low-level southerly flow. Temperatures at h85 will continue to rise for the first half of the following week, reaching the upper teens to low 20s by Monday evening. This would more than shatter the observed record for a LBF sounding in October should it materialize as advertised by NWP guidance, further backing the thought that temperatures will return to above normal values very quickly. Have a return to upper 70s to low 80s for daytime temperatures on Monday and Tuesday but given the magnitude of the anomalously warm air moving it, those values may increase in subsequent forecasts. Dry weather is largely expected to continue through the end of the forecast period.

AVIATION. (For the 00Z TAFS through 00Z Wednesday evening) Issued at 614 PM CDT Tue Sep 29 2020

VFR will continue for western and north central Nebraska through the forecast period. However, wind will be an aviation weather concern tomorrow. Northwest winds will rapidly strengthen through the morning with gusts 30+ kts during the afternoon.

LBF WATCHES/WARNINGS/ADVISORIES. Red Flag Warning until 7 PM CDT /6 PM MDT/ this evening for NEZ210-219.
