Area Forecast Discussion National Weather Service Phoenix AZ 1130 AM MST Mon Oct 18 2021

UPDATE. Updated 18Z Aviation Discussion.

SYNOPSIS. A weak cold front will move through the area resulting in somewhat cooler temperatures today and Tuesday. Breezy conditions can be expected area-wide today, with the strongest winds expected in southeast California. Otherwise, high pressure will build back into the region during the latter half of the week allowing temperatures to rebound back near the seasonal normal. Dry weather should persist through at least the end of the week.

DISCUSSION. A large Pacific upper trough is well-defined on water vapor imagery this morning, with the primary circulation centered near Sacramento as of 09Z. Arizona and southern California are within a dry slot positioned along the basal portion of the trough, with 00Z soundings sampling between 0.2-0.5 inch of PW within this region. A belt of strong 850-700 mb westerly flow will spread southeastward across southern California, and bring an increase in surface winds later this morning and afternoon. Early morning observations show localized gusts of 20-25 mph are already occurring across parts of southwest Imperial County. Expecting gusts to 30-40 mph to become more common by early afternoon across this area, with potentially localized gusts exceeding that west of El Centro. Farther east, wind gusts of 20-30 mph can be expected, including across the Phoenix metro area. The belt of strongest flow should remain focused to the north of our forecast area across northern Arizona, which should preclude advisory-level gusts from materializing. Much weaker winds are forecast on Tuesday as the trough accelerates to the east.

The other notable impact will be the modest cool down in temperatures. Highs today will be several degrees below normal and only top out in the upper 70s to lower 80s across the lower deserts. Temperatures may cool an additional couple degrees into Tuesday with Phoenix expected to top out right at 80 degrees. Temperatures will warm back closer to normal mid-week as quasi- zonal flow becomes established. Majority of ensemble guidance favor strong mid-level flow anomalies persisting across the eastern Pacific and edging into the West Coast, with the potential for one or more low-amplitude storm systems next week and beyond. Impacts from this configuration are likely to primarily be periods of potential breeziness and temperatures kept closer to seasonal normals, with higher precipitation chances likely remaining focused farther north.

AVIATION. Updated at 1830Z.

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT: Winds will gradually veer through early-afternoon with an extended period of southerly crosswinds expected. Speeds will also gradually increase and become more gusty, peaking around 10-13 kts with gusts up to 20-25 kts. Winds should subside beginning around sunset. The cumulus that developed this morning with bases around 6 kft may persist through the evening at the same altitude, but vary in coverage. A similar development of cumulus is likely again Tuesday morning, but may initially be as low as 3-4 kft before climbing to 6 kft.

Southeast California/Southwest Arizona including KIPL and KBLH: Strong gusty winds are already ongoing this morning and likely to persist through the afternoon. There is even evidence of mountain waves and rotors in the Imperial Valley this morning. Sustained winds up to 20-25 kts and gusts up to 30-35 kts will be possible through the afternoon at both terminals, favoring the west at KIPL and southwest at KBLH. Winds may also generate enough blowing dust to briefly lower visibility. Any lofted dust around sunset could also impact slantwise visibility. Winds will weekend this evening, becoming light Tuesday morning.

FIRE WEATHER. Wednesday through Sunday: High pressure will build back across the Southwest in the wake of an early week storm system, bringing generally light and diurnally driven winds. Temperatures will climb back into the upper 80s to near 90 Thursday through the weekend. Min afternoon RH values will mostly fall between 10-20% across the lower deserts to 20-25% across the high terrain. Overnight recoveries will mostly reach between 30-50% through the period.

SPOTTER INFORMATION STATEMENT. Spotters should follow standard reporting procedures.
