Winds this strong can make driving difficult, especially for high profile vehicles. In addition, strong winds over desert areas could result in briefly lowered visibilities to well under a mile at times in blowing dust or blowing sand. Use extra caution. && $$

Area forecast discussion, Mar 13, 10:43 PM MST, 3 hours 40 minutes before
Area Forecast Discussion National Weather Service Phoenix AZ 1043 PM MST Sat Mar 13 2021 .UPDATE... Updated 06Z aviation discussion. && .SYNOPSIS... The slow moving low pressure weather system will continue to bring mostly light shower and isolated thunderstorm chances to the eastern half of Arizona this afternoon and evening and cool conditions for one more day. Temperatures will warm to just shy of normal for Sunday and Monday, but a passing dry weather system late Monday into Tuesday will lower high temperatures back into the 60s on Tuesday. This fast moving weather system will also bring a period of breezy to locally windy conditions on Monday. Warming conditions through the latter half of next week should push high temperatures well into the 80s by next Thursday or Friday. && DISCUSSION... The slow moving UL closed low pressure system was centered just west of the 4-Corners area with the H5 trough axis and corresponding cold core migrating through E AZ east of Phoenix with northwesterly flow aloft. Afternoon WV imagery shows the associated elevated moisture field, including wrap-around moisture, passing through the area with a number of vort lobe clusters/mini PVA disturbances rotating around it. This included an upstream mesoscale trough axis on the west flank of the main low northwest of the region. SPC mesoscale analysis and the latest ACARS soundings confirm a relatively elevated BL and mid-level moisture profile with a saturated layer extending from near 760-650 mb and PW values near 0.45". The analysis also indicated weak CAPE/instability. Early afternoon radar showed a large area of scattered popcorn showers and an isolated thunderstorm mainly to the E-NE-SE of the Phoenix Valley. Another modest area of rain and showers associated with the next mini disturbance was near Lake Pleasant and Black Canyon City. Visible satellite indicated slightly drier air and a CU field west of Phoenix. The HREF CAM family is in good agreement on a temporary lull in shower activity with some drier air moving in from the west for mid afternoon, with another small round of showers developing in NE Maricopa County northeast of Phoenix associated with another mini-lobe for the late afternoon. Then a final wrap-around lobe disturbance is likely to trigger the last round of mostly light and some moderate showers in the Phoenix area during this evening after sundown. In the last 3 days Sky Harbor has received 0.37" of rain. Another ~0.02-0.07" of precip for Sky Harbor can not be completely ruled out for this evening and/or tonight. In addition, forecast soundings indicate a ground fog signature for early Sunday morning. Highs today will be around 16-20 degrees below normal with highs topping out in the mid to upper 50s to near 60. On Sunday the low pressure system exits to the east and recovering heights ahead of a brief high pressure system early Monday will allow temperatures to rebound into the upper 60s to low 70s on Sunday and low-mid 70s for Monday. Late Monday into Tuesday ensembles are in good agreement on ushering in a very progressive compact Pacific closed low pressure system from the northwest, although there is some uncertainty on its latitudinal position. The most likely positions range from N-Central AZ to the 4-corners. A slight ensemble preference for a slightly more southerly track has resulted in some fleeting increased POPs for the Phoenix and NE Maricopa cty area for Monday evening and night. However the main moisture field continues to favor areas further north. What is more certain is the prospect of very breezy to windy conditions for SE CA and SW AZ for Monday afternoon and evening. Areas of blowing dust may also be a concern for that area. In addition enough CAA is expected to drop highs back down into the mid 60s for Tuesday. For the later half of the week the cluster analysis favors the development of a strong to very strong anomalous ridge of high pressure over the west-Central CONUS and the Desert Southwest. The heat signature pattern is likely to result in highs in the low 80s by Thursday, and the mid-upper 80s by Friday. && .AVIATION...Updated at 0542Z. South-Central Arizona including KPHX, KIWA, KSDL, and KDVT: Aside from westerly wind gusts on Sunday afternoon, minimal aviation concerns are expected through the TAF period. Light and variable winds will become easterly at 5-10 knots late in the overnight hours. A brief period of low-level wind shear around sunrise is possible if E-SE winds increase above 10 knots against westerly 15-20 knots just 1-2 kft above the surface. However, confidence is too low to include this in the TAF at this time. Westerlies should return by early afternoon with gusts up to 20 knots by late afternoon before subsiding by early evening. Shower activity has passed southeast of the region, with only lingering SCT 8-10 kft ceilings for the next couple hours. Southeast California/Southwest Arizona including KIPL and KBLH: Minimal aviation concerns are expected through Sunday evening as west- southwest winds generally remain below 15 knots under clear skies. A brief period of gusts up to 20 knots will be possible at KBLH during the afternoon hours, but conditions otherwise should be much calmer than they have been for the past few days. && .FIRE WEATHER... Monday through Friday: A mostly dry weather system will track across northern Arizona late Monday into early Tuesday. This system will bring locally windy conditions Monday afternoon, especially across southeast California and southwest Arizona where gusts of 30-40 mph are likely. Minimum afternoon humidity levels in a 15-25% range are expected for Monday, lowering to around 10-15% by Wednesday. After a cool day on Tuesday, temperatures will quickly warm to well above normal by Friday. Humidity levels late next week will also remain low with minimum readings in the single digits to around 10%. Overnight recoveries early in the period will mostly reach 40-50%, before dropping to 25-35% late next week. && .SPOTTER INFORMATION STATEMENT... Spotters should follow standard reporting procedures. && .PSR WATCHES/WARNINGS/ADVISORIES... AZ...None. CA...Wind Advisory until 10 PM PST this evening for CAZ562. && DISCUSSION...Sawtelle AVIATION...Hopper FIRE WEATHER...Kuhlman
