Area Forecast Discussion National Weather Service Phoenix AZ 206 PM MST Sun Dec 8 2019
SYNOPSIS. Abundant moisture will continue to bring cloudy skies with isolated showers across the lower deserts this afternoon. Additional isolated to scattered showers are possible again Monday morning and afternoon. Afterwards, drier conditions with near to slightly above normal temperatures are then expected for the rest of the week.
DISCUSSION. Water vapor imagery shows an upper level low centered over California with a strong subtropical jet that continues to funnel abundant moisture into the Southwest. Thick overcast clouds and generally moist conditions will keep temperatures cooler than normal with highs struggling to reach the mid 60s. Shower activity on radar has quieted somewhat over the last hour with just a few weak showers in the forecast area. For this afternoon and evening, several models indicate showers redeveloping along the higher terrain north and east of Phoenix and south of the Valley over Pinal County. The Phoenix area may see some isolated activity but the areal extent of rainfall will be less compared to yesterday.
On Monday, scattered convective showers will be possible late morning and afternoon as instability increases when the cold core of the low passes overhead. Farther west, tightening of the pressure gradient will create breezy conditions across southeast California and along the lower Colorado River. By Monday night, the low will be southeast of the forecast area and our conditions will begin to dry.
A dry disturbance will pass to our north keeping atmospheric heights suppressed through midweek. As such, daytime temperatures will remain near seasonal normal values before a ridging takes hold later in the week allowing the 70s to return.
AVIATION. Updated at 1854Z.
South-Central Arizona including KPHX, KIWA, KSDL, and KDVT: Occasional light rain will persist across the Valley through mid-afternoon. Thereafter, activity will become somewhat more scattered, but with the potential for embedded heavier cells. The threat for scattered showers will continue overnight and into Monday, with the highest probabilities located south and east of Phoenix. Meanwhile, abundant low-level moisture will promote the development of low stratocu after midnight ahead of an approaching low pressure system. Several hours with ceilings as low as 3k feet are possible, which will likely persist through much of Monday morning. Otherwise, the cloudiness will disrupt the typical terrain-driven circulation, resulting in periods of light and variable winds.
Southeast California/Southwest Arizona including KIPL and KBLH: Earlier fog has dissipated, though MVFR visibilities persist in some areas. Conditions are expected to improve later this afternoon as westerly winds increase. Latest guidance suggests winds could reach 20 kt at KIPL, before subsiding during the evening. Another period of breezy conditions is favored further north near KBLH Monday morning.
FIRE WEATHER. Tuesday through Saturday: Dry conditions will prevail under high pressure aloft. Minimum humidity levels initially will be around 30-40% early in the period, but will fall to 25-30% beginning Thursday. Overnight recovery will still be good to excellent. Winds through the entire period with be fairly light with little to no breeziness.
SPOTTER INFORMATION STATEMENT. Spotters should follow standard reporting procedures.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
