What forecasters said that day
The local office's own words before this high wind warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Flagstaff, AZ wrote its last area forecast discussion before this high wind warning went out at Mar 28, 9:30 PM MST, 5 hours 48 minutes earlier.
Area forecast discussion, Mar 28, 9:30 PM MST, 5 hours 48 minutes before
Area Forecast Discussion National Weather Service Flagstaff AZ 930 PM MST Tue Mar 28 2023 .SYNOPSIS...Warn and windy conditions are expected on Wednesday ahead of storm system that is expected to bring rain and high elevation snow to the region on Thursday. Dry conditions with warming temperatures then return for Friday into the weekend. && .UPDATE...Latest guidance this evening has come in with a bit better dynamics for the upcoming system, with the GFS the most bullish and coming in quite a bit wetter than the other guidance. Both QPF and PoPs were adjusted for the Wednesday night-Thursday night timeframe to keep within the envelope of the latest guidance a bit better. Since QPF increased, snow amounts increased a tad over the higher terrain with this evenings update. However, given the gusty winds and marginal temperatures during the daytime on Thursday, snow ratios (and consequently amounts) will likely not be very high. The current forecast calls for around 2-4 inches in the upslope areas over the Kaibab Plateau and the Mogollon Rim and a Trace-2" elsewhere above 6000 feet. The most intense rain and snow looks to move into the region Thursday morning, as strong frontogenetic forcing moves into region. Outside of that timeframe, less intense isolated to scattered rain and snow showers will be possible. While accumulations are not forecast to be significant, hazardous driving conditions will be possible due to poor visibility and snow covered roads. Gusty winds may also further hamper travel with patchy blowing and drifting snow. Beyond the Wednesday/Thursday timeframe, the afternoon forecast package remains on track and unchanged. Previous discussion continues below. && .PREV DISCUSSION /231 PM MST/...After a period of tranquil weather, our next upper level low, currently across the Pacific NW, is forecast to dive southward along the California coastline through the day on Wednesday. Thereafter, the multi-model grand ensemble projects that this low will transition more into an open wave as it slides through the Four Corners region. Wednesday and Thursday offer the best opportunities for precipitation and wind gusts in excess of 30 mph. On Wednesday, the low level height gradient is expected to tighten resulting in a conveyor of 40 to 45 knot flow aloft across the western Coconino and Kaibab Plateaus as well as the higher terrain of Yavapai County. Around 80-90% of NBM v4.1 membership advertises peak wind gusts in excess of 40 mph across these aforementioned areas on Wednesday and as a result a Wind Advisory has been hoisted for these regions. Other areas that may approach 40 mph wind gusts include locales downwind of the Mogollon Rim and across the Black Mesa. At this juncture, probabilities are lower for areas along and east of the U.S. HWY 89/I-17 corridors on Wednesday, but we'll need to evaluate the next suite of NWP this evening and into early tomorrow morning. The active weather pattern will continue late in the day on Wednesday and into the pre-dawn hours on Thursday, as the first wave of precipitation is forecast to develop near the CA/AZ/NV border. The tail end of the 12 UTC HREF guidance suggests that initial bands of precipitation will slide into the western Coconino and Kaibab Plateaus with the upslope machine cranking up along the central and eastern Mogollon Rim. Enhanced surface flow (40 to 50+ mph wind gusts) downwind of the higher terrain features are common in this pattern and we'll need to monitor for any wind headlines Wednesday night into Thursday along the Mogollon Rim. Late Wednesday through sunrise Thursday, the greatest precipitation chances (20%-60%)reside along the central Mogollon Rim/SF Peaks and areas west of US HWY 89. 1-2" snowfall amounts forecast largely above 6500' elevation during this period. Through the day on Thursday, the mid/low level height gradient intensifies initially as the main upper trough approaches. With intermittent periods of moderate snow, the Thursday morning commute may be slick and hazardous, especially across areas above 6500' elevation. The height gradient will tighten most noticeably along the eastern Mogollon Rim and White Mountains area after sunrise. With the percentage of NBM membership with wind gusts of 60 mph or greater around 90%...a High Wind Watch has been issued for the White Mountains area. Additional wind headlines may be required for the rest of the High Country, but at this time, there's still a little too difficult to discern which areas may experience the strongest winds. Regardless, individuals across the area should secure any loose outdoor articles and be prepared for difficult driving conditions (due to the combo of wind and precipitation). With 50 to 55 mph winds some impacts to power infrastructure cannot be discounted. Thursday afternoon and into Friday evening offered the opportunity to make the most noteworthy changes to the PoP/QPF fields from the NBM. While flow aloft becomes a bit more westerly, mid-level moistening in both 2D plots and forecast soundings takes place as 120 meter height falls overspread the area. Forecast soundings also reveal the presence of 100-300 J/kg of CAPE, most noticeably north of I-40. With the cooler pocket of air aloft, mid-level moistening, and instability, there will be a thunderstorm risk. Brief bouts of intense snowfall rates (1-2"/hr) cannot be discounted and it is within these deeper showers and storms that travel will become extremely dangerous due to visibility under 1 mile, winds in excess of 30 mph, and slick roadways. The most likely time frame for these bouts of showers and thunderstorms will be Thursday afternoon and into Thursday evening and the preferred area will generally be along and north of I-40. As a result, the Thursday afternoon/evening commute may be challenging due to these showers and isolated storms. Storm total snow amounts (Wednesday Evening - Friday Morning) for the area actually reside within the 50th to 75th percentile of the NBM (on average 2 to 4 inches for locations largely above 6500'). Worst case scenario (NBM 90th percentile) would result in storm total snowfall closer to 3 to 6 inches across the High Country. Should showers and thunderstorms become more widespread than currently anticipated, the 90th percentile snow accumulations may offer a more reasonable forecast. Precipitation is forecast to exit stage right (to the east in our case) by midnight Friday. Wind gusts will abate below 40 mph with largely uneventful weather this weekend and into next week. The coldest night appears to be Friday morning with temperatures in the teens and twenties across the mountains to thirties and 40s elsewhere. The upper air pattern remains largely zonal into next week, but limited moisture precludes mentioning any precipitation in the forecast. Technically, the greatest PoPs are around 10% along the UT/AZ/CO border Monday and into Tuesday, but we'll examine the need for higher precipitation chances with subsequent forecasts. && .AVIATION...For the 06Z TAF package...VFR conditions will continue through the TAF period. South to southwest winds 5 to 15 knots, increasing after 17Z to 15 to 25 knots with gusts up to 35 knots. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Dry and warmer conditions continue Wednesday, with southwest winds increasing to 15 to 25 mph and gusting as high as 35 to 45 mph. Winds remain gusty Wednesday night, with rain and snow moving in west to east late at night. Strong southwest winds are in the forecast for Thursday, along with a good chance of rain and snow. Friday through Sunday...Dry conditions return on Friday through Sunday, with a warming trend. Decreasing winds turn westerly on Friday, variable on Saturday and then return to southwesterly on Sunday. && .FGZ WATCHES/WARNINGS/ADVISORIES...
