Area Forecast Discussion National Weather Service Phoenix AZ 956 PM MST Fri Oct 15 2021

UPDATE. Updated 06Z Aviation discussion.

SYNOPSIS. High pressure over the region will yield mostly clear skies and quite seasonable temperatures through the weekend though periodically breezy conditions will be common through south-central Arizona. A weak cold front will result in somewhat cooler temperatures Monday and Tuesday, however subtle warming will resume Wednesday and Thursday. Dry weather is expected through the end of next week.

DISCUSSION. A progressive pattern will continue through early next week with modest ridging building into the SW Conus. Marked height and thermal increases have already been evident per objective analysis and ACARS in-situ sampling with better than 5C warming in the H7-H5 layer. Correspondingly, surface temperatures have warmed and forecast afternoon highs will push back very near the seasonal normal through the weekend (and some 10F-15F warmer than the past several days). However, the increased ridging pattern has resulted in stronger surface pressure rises over the Great Basin; and combined with the seasonally typical Gulf of California thermal low pressure, breezy east to northeast boundary layer winds will be common through much of central AZ. Nocturnal breezy conditions will be most evident over ridge tops, however should readily descend into lower elevations Saturday with mid/late morning mechanical mixing yielding gusts 20- 30 mph through much of region surrounding the Phoenix metro.

Early next week, a strong yet compact negative PV anomaly will propagate from the northern CA coast into the Great Basin dragging a weakening cold front inland. While mid and upper tropospheric winds strengthen, moisture along the frontal boundary should be extremely shallow and scoured along the California coast range leaving only residual cirrus streaming into the forecast area. Little ensemble spread has been exhibited with this system remaining well north of the CWA and forecast confidence is excellent that notable impacts from this system will primarily be limited to breezy conditions over SW Imperial County. Wind anomalies associated with this system do not appear to be resounding, so merely just some typical afternoon breeziness for the majority of the area looks valid. Otherwise, temperatures will cool only a few degrees behind the decaying front, but quickly rebound during the second half of the week as the next shortwave ridge moves over the region.

AVIATION. Updated at 0456Z.

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:

Strong surface high pressure centered over the 4-corners region will keep winds from an easterly to northeasterly direction through the TAF period. Light northeasterly winds will continue through the overnight hours at all of the PHX area terminals. In addition, winds in the lower levels above the surface will strengthen towards morning (as high as 40 kts at 020 AGL). Thus, have included LLWS in the TAFs during the early morning hours. Breezy easterly surface winds develop by 16Z or so on Saturday with gusts to 20kts (locally higher at times). These easterly winds are expected to diminish somewhat by Sat afternoon as low-level pressure gradients begin to relax. skies to remain CLR through the TAF period.

Southeast California/Southwest Arizona including KIPL and KBLH: Strong surface high pressure centered over eastern Utah will drive northeasterly winds in the lower troposphere through the rest of the afternoon, with a trend toward east tonight and southeast on Saturday. Surface winds will favor a northwest-west direction at KIPL and a northerly direction at KBLH through the TAF period. skies to remain CLR through the TAF period.

FIRE WEATHER. Sunday through Thursday: High pressure and dry conditions are likely to prevail across the region through the period with temperatures near seasonal normals on Sunday falling to slightly below normal by mid-week. Locally breezy conditions will be possible on Sunday and morning in southeast California and the lower Colorado River Valley as a dry storm system moves across the Southwest. Min afternoon RH values will mostly fall between 10-15% across the lower deserts to 20-25% across the high terrain. Overnight recoveries will mostly reach between 25-45% through the period.

SPOTTER INFORMATION STATEMENT. Spotters should follow standard reporting procedures.
