(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus65 ktwc 170406 afdtwc area forecast discussion national weather service tucson az 906 pm mst Tue jul 16 2019 Synopsis After another hot day across much of the area this afternoon, a few showers will linger overnight. A better flow regime will likely increase thunderstorm coverage Wednesday afternoon into Wednesday night. Scattered mainly afternoon and evening thunderstorms with temperatures returning to near normal Thursday into early next week. Discussion We tied a record in tucson with 110 today. Weakening high pressure and increasing moisture is still expected to tamp that down several degrees Wednesday afternoon. We're already seeing increasing moisture from both the northern gulf of california (surface dew points in the mid to upper 50s pushing into western pima county) and strong outflow from organized convection south of the border in sonora. This will set the stage for an organized thunderstorm complex in far northern sonora, creeping into portions of santa cruz and the southern half of cochise county tomorrow afternoon. That would subsequently increase storm chances further north and west by late in the afternoon and early evening (probably including tucson). Our current forecast handles this pretty well. Modest update earlier to show the decreasing activity after 03z this evening, otherwise things look on track. Heavy rainers a concern tomorrow afternoon and evening night. Please see the previous discussion below for additional details. Aviation Valid through 18 06z. Diminishing -shra overnight with partial clearing. Some outflow possible from convection south of the border overnight, otherwise normal diurnal trends. Surface wind Wednesday afternoon swly- nwly 10-15 kts with gusts to 20 kts. Storm and shower chances increase tomorrow afternoon along with increased cloud cover. These will be accompanied by strong erratic outflow winds. Aviation discussion not updated for TAF amendments. Fire weather Increased moisture and a better flow regime should enhance thunderstorm coverage Wednesday afternoon into Wednesday night. Thereafter, scattered mainly afternoon and evening thunderstorms Thursday into early next week. Expect brief |
strong, gusty and erratic winds near thunderstorms. Otherwise, 20-foot winds will be mainly under 15 mph. Climate Tucson international airport tied a record today with 110 (2003). It was also the first 110 of the year. Prev discussion Another very hot day across southeast arizona with an excessive heat warning in effect through 8 pm mst this evening across parts of southeast arizona. Upper air plots this morning placed upper high over the new mexico boot with weak south to southwest flow aloft over the area. Pw values are slightly down versus 24 hours ago with values ranging from 0.90" to 1.30" with highest values along the international border with even higher values across sonora mexico. Radar was showing widely scattered thunderstorms over the higher terrain south and east of tucson. Best area for storms, per latest high resolution models, will be across santa cruz and southern cochise county, especially from the patagonia mountains to the mule mountains, with brief heavy rain, hail and strong gusty winds being the main concerns. Tucson may see some weak storms move across the metro area, thanks to outflows from the south southeast, between 4 and 7 pm. High resolution models suggesting a gulf surge overnight into Wednesday. Normally there is a one day delay for widespread convection, but the models are suggesting that areas south of a sells to tucson to willcox line will see scattered to numerous showers and thunderstorms tomorrow afternoon into the evening hours where a nice 700 mb theta-e ridge is forecast to be. Pw values are forecast to be between 1" and 1.60" with highest values from tucson south. So main threat with storms tomorrow will be wet microbursts, especially south of tucson. Could easily see very localized rainfall rates of 1"-2" across eastern santa cruz and southwest cochise counties. Wpc has the southern portions of the forecast area under a marginal ero, excessive rainfall outlook, tomorrow afternoon and evening. Not as hot tomorrow thanks to the added moisture. Scattered mainly afternoon and evening thunderstorms with near normal temperatures to prevail Thursday into early next week. Twc watches warnings advisories None. Meyer g visit us on facebook...

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. |
