12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Tucson AZ 827 AM MST Sun Aug 9 2020
SYNOPSIS. High pressure over the region will result in well above average daytime temperatures this week, as well as below average daily thunderstorm chances. Thunderstorm chances will remain primarily well south and east of Tucson, as a drier southwesterly flow limits thunderstorm coverage into at least the middle of the week.
DISCUSSION. Clear skies across much of southeast Arizona attm, with some mid level clouds noted over central/western Pima county and in the White Mountains. Surface dew points were generally in the 40s across the forecast area, with some lower 50s along the International Border. The KTWC 200809 12Z sounding is even less promising for shower/thunderstorm development versus 24 hours ago, with PW down to 0.94", virtually no CAPE and southwest/west flow above 700 mb. Expect any showers and/or thunderstorms that develop today to be well south and east of the Tucson Metro area, roughly east of a line from Nogales to Mt. Graham to Hannagan Meadow - and only isolated development at that.
Otherwise, high temperatures will top out 6-10 degrees above normal across southeast Arizona today, with upper 90s to near 100 degrees across Santa Cruz/Cochise counties, 102-107 in the lower elevations of Graham, eastern Pima and Pinal counties and 105-110 across central/western Pima county.
Overall, current forecast looks on track. No updates this morning. For more information on the latter periods of the forecast, please refer to the PREV DISCUSSION section below.
AVIATION. Valid through 10/18Z. FEW-SCT clouds 10-15k MSL through much of the forecast period with SCT-BKN clouds possible this afternoon into evening for KOLS/KDUG terminals. Isolated -TSRA/-SHRA this afternoon and evening mainly along the Int'l border from KOLS eastward and White Mountains. SFC wind less than 12 kts and variable in direction thru the forecast period. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Hot and dry weather continues for much of southeast Arizona this week. A few showers and thunderstorms are possible this afternoon and evening mainly along the International border from Nogales eastward and for the White Mountains. Thereafter, dry weather is expected areawide Monday through Wednesday, with perhaps a gradual increase in moisture later in the week and a slight chance of thunderstorms for the higher terrain. 20- foot winds will generally follow typical diurnal patterns at less than 15 mph. However, this dry and hot regime will be more conducive to producing gusty outflow winds should thunderstorms develop nearby.
PREV DISCUSSION. We continue to see a broad ridge across southern tier states with weak troughiness near the west coast. The resulting southwesterly to westerly flow over our area continues to keep moisture levels well below average for the middle of the Monsoon. Surface dew points are even dropping into the upper 30s in some locations as we struggle to maintain precipitable water values near 1 inch. Daily variations are running 60 to 70 percent of normal. Thus, the meager thunderstorm forecast will continue to combine with a high temperature forecast several degrees above average for mid August. Something more like a typical late June day.
Newly formed Tropical Storm Elida, currently about 220 miles south of Manzanillo Mexico, doesn't look like much help this far north. With the broad ridge in place over our area, she will likely track west, well south of the Baja Peninsula.
The ridge is expected to strengthen westward over the next several days, with a high center reconsolidation nearly overhead the second half of the week. Afternoon highs 10 to 14 degrees above average will probably push past Excessive Heat levels by Thursday and Friday (maybe a little earlier). Low-grade Monsoon forecast until further notice.
TWC WATCHES/WARNINGS/ADVISORIES. None.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
