(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus65 ktwc 171607 afdtwc area forecast discussion national weather service tucson az 907 am mst Sat aug 17 2019 Synopsis Thunderstorm activity will be lvery imited this weekend with above normal temperatures continuing. Excessive heat will return next week with an uptick of thunderstorm chances for the second half of the week. Discussion An anti-monsoon pattern remains in place this morning with dry westerly flow aloft at nearly all levels of the atmosphere. This is readily apparent with pw (atmospheric moisture) running well below normal, generally near the 10th percentile level for mid august. Thanks to the high heights and thicknesses, mid-level atmospheric temperatures are too warm for decent instability without a significant intrusion of moisture which isn't in the cards. So just based on that little if any convection is expected today with the possible exception of the SE third of cochise county where pw values are a bit higher. This scenario is pretty much what most of the cam solutions are pointing to as well so we look good there. It will continue to be a good deal warmer than average (tucson's average high is 97 now) but not to the extent of several days ago. Current forecast is on track and see no reason for any updates at this time. Aviation Valid through 18 18z. Skc-few clouds at 11k-15k ft msl west of ktus and few-sct clouds at 9k-13k ft msl (locally bkn) east and south of ktus. Slight chance of -tsra -shra along the international border from kols to kdug, including kalk, between 17 20z and 18 03z. Sfc wind less than 12 knots and favoring a wly nwly direction in the afternoon early evening with a few afternoon gusts to around 20 kts. Aviation discussion not updated for TAF amendments. Fire weather Limited moisture through Wednesday of next week, with any shower thunderstorm development confined to along the |
international border from nogales eastward. Temperatures will moderate a little this weekend, but will still remain above normal. Thunderstorms that do develop may produce gusty and erratic outflow winds, otherwise light winds with normal diurnal trends are expected. Excessive heat will return next week with temperatures around 10 to 12 degrees above normal next Tuesday and Wednesday. A strong moisture increase is then expected during the middle to latter half of next week, with thunderstorm coverage increasing and shifting westward through the week. Prev discussion issued 244 am mst Sat aug 17 2019 a drier westerly flow pattern will persist into early next week resulting in limited thunderstorm activity. This flow pattern will also bring some relief in the excessive heat of the past few days. However, there will not be too much relief as daytime temperatures remain several degrees above normal. Models were in good agreement with high pressure aloft building northward by the middle of next week. This northward shift in the upper high's position will turn up the heat during the early part of the week then open the door up for deeper moisture to return. That said, there continued to be more confidence in another round of excessive heat Tuesday and Wednesday of this coming week. Thus, an excessive heat warning has already been posted for portions of southeast arizona on Tuesday and Wednesday. This excessive heat episode will be followed by an upswing in thunderstorm activity as early as Wednesday into next weekend. Twc watches warnings advisories Excessive heat warning from 11 am Tuesday to 8 pm mst Wednesday for azz501-502-504>506-509. Public... Cerniglia davis aviation... .Zell fire weather...

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. |
