Aviation
Updated at 0610Z.
South Central Arizona including KPHX, KIWA, KSDL, and KDVT: The main aviation concern remains the potential for multiple windows of convection and its associated operational hazards. The first round early tonight (through about 10Z) has lower confidence regarding direct impacts at the terminals, but PROB30 groups have been maintained to address this uncertainty. There is better confidence regarding the second round of TS activity Wednesday afternoon/evening between 19-01Z. Timing may need to be adjusted based on future forecast trends, but TEMPO groups have been carried over from the previous forecast as a reflection of higher certainty. Low CIGs down to 5-6 kft, gusty and erratic winds, and sub- VFR surface VIS will accompany any TSRA that moves near or over the terminals.
Outside of convective windows, winds will maintain some degree of an E'rly component through Wednesday evening with a S'rly tilt to the flow during the afternoon hours. SCT-BKN skies will be common across the region.
Southeast California/Southwest Arizona including KIPL and KBLH: No major aviation concerns are expected during the TAF period. Outside of extended periods of VRB conditions, S'rly flow will be favored at KBLH, with some gusts upwards of 20-25 kt during the afternoon hours, while winds at KIPL will take on familiar diurnal trends, flipping between SE and W. FEW-SCT skies will be common through Wednesday evening, with the lowest bases around 6-7 kft.
Fire Weather
Wind speeds today will generally remain light with limited afternoon gustiness before increasing towards the middle of the week ahead of an approaching weather system. Mainly dry conditions will prevail this afternoon before rain chances increase substantially Wednesday and Thursday with significant rainfall amounts, in excess of 1.00", likely across the higher terrain areas of the eastern districts. MinRHs today will range between 30-50% before increasing above 50-60% across the eastern districts Wednesday and Thursday along with good to excellent overnight recoveries. Temperatures will be in a near normal range tomorrow before falling into a below normal category by the end of the week and lasting through the weekend.
