UPDATE. Updated Aviation Discussion.
SYNOPSIS. Slightly cooler temperatures today will give way to much warmer temperatures over the next several days. As we move into mid week, high pressure will strengthen yet again allowing hotter deserts to approach or exceed the 110 degree mark. Increasing moisture may also bring a slight chance of thunderstorms to southern Gila County through at least the middle of the week before drying sets into the area Friday into the weekend.
DISCUSSION. Visible satellite imagery this afternoon showed convection across parts of southeastern and northeastern Arizona, while activity was beginning to increase across southern Gila County. PWAT values and instability will be slightly better than yesterday, so expect slightly better coverage of thunderstorms this afternoon and early evening. Primary threats with any storms will be strong outflow winds, localized blowing dust, and lightning. Could see an outflow from storms to the south make it into Phoenix, but latest guidance keeps any outflows that make it into the metro fairly weak. Otherwise, afternoon highs will be cooler today only topping out around 105 in Phoenix.
A cutoff low in the east Pacific near the Baja California coast will aid in amplifying the upper level ridge further west over the Desert Southwest over the next several days. As this occurs, temperatures will increase through mid week with temperatures nearing or exceeding 110 degrees across much of the lower deserts by Wednesday. NAEFS percentiles show 500 mb heights climbing above the 90th percentile across much of the state Wednesday and Thursday. Ensemble guidance continues to trend warmer for this week with the potential for excessive heat expanding. The latest HeatRisk now shows increased coverage of high heat risk across southwest Arizona and the lower Colorado River Valley. As a result, these areas have now been added to the Excessive Heat Watch for Wednesday and Thursday.
By Friday, the cutoff low moves northeast across the state, bringing increased breeziness to the region. The increase in winds Friday combined with low RHs will promote an enhanced fire danger across the state. Temperatures will also fall to near seasonal normal values by the end of the week, with the NBM showing temperatures near to slightly below 100 degrees across the lower deserts Saturday.
AVIATION. Updated at 0010Z.
South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:
Mainly diurnal wind directions are expected through the period with lingering westerly wind gusts around 15-18 kt during the early evening hours. Some lingering distant thunderstorms well to the east and southeast of the Phoenix area are possible early this evening. FEW-SCT mid to high cloud decks will possibly become BKN around 15 kft overnight and into Tuesday morning. Strong outflows are not expected in the area this evening and tonight except for possibly at KIWA later this evening around 02-05Z.
Southeast California/Southwest Arizona including KIPL and KBLH:
FEW-SCT mid to high clouds will increase over the region overnight to become occasionally BKN near 12-25 kft into Tuesday morning. Winds will be rather light and variable at KIPL through the period. Breezy southerly winds early this evening with gusts near 18 kt are expected at KBLH early this evening. Winds will become light and variable late tonight and into Tuesday morning. Occasionally breezy southerly winds will develop at KBLH Tuesday afternoon with gust reaching 20 kt.
FIRE WEATHER. Thursday through Monday: Moisture may remain ample enough for isolated afternoon thunderstorms mainly Thursday and Friday across much of eastern Arizona, including Gila County. Storms farther west into the lower desert area around Phoenix is less likely. Storms are not likely to produce much rain, but may create strong gusty winds, outflows, and lightning strikes. Otherwise, winds are likely to follow typical diurnal directional trends with some afternoon breeziness. Winds look to be strongest on Friday as an upper low moves across the region. High temperatures will stay well above seasonal normals through Thursday with hotter deserts up to around 110 Wednesday and Thursday. Cooler air will filter into the area Friday into Saturday lowering highs to near the 100 degree mark. Minimum humidity values will drop into the 10-15% range with overnight recoveries rising into the 30-40% range. Even though these elements remain well below critical thresholds, the fire danger will remain heightened.
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.
