Increasing moisture will bring increasing thunderstorms to the area with temperatures falling back to near normal by Friday into the weekend. Discussion Several heat records fell around the area today, but tucson airport came up 1 degree short. More of the same for much of the area tomorrow, however a moisture increase is underway with outflows from new mexico pushing into cochise county this evening. Easterly winds around 15kts at douglas and dew points jumped from 38 to 49 over the past 90 minutes. Our moisture increase from direct outflow from the east and south, and a moderate gulf surge working it's way into the northern gulf. We should be back in business with a strong fetch of deeper moisture Thursday night into Friday and Saturday. A strong increase in thunderstorms and temperatures falling back to near normal is still a solid forecast trend. Please see the previous discussion below for additional details. Aviation Valid through 22 06z. Few-sct clouds at 12k-16k ft msl thru the forecast period. There is a slight chance of -tsra -shra near the az nm border including near kdug and across the white mountains into late this evening. Isold- sct -tsra -shra redevelop Wednesday afternoon from ktus kols eastward. Sfc wind generally nwly into this evening at less than 12 kts with a few gusts to 15-20 kts. Terrain driven winds less than 10 kts persist overnight with SW to NW winds Wednesday afternoon mainly less than 12 kts. Aviation discussion not updated for TAF amendments. Fire weather Better coverage of showers and thunderstorms begin tomorrow mainly east of tucson and spread westward and northward into Saturday. Near record high temperatures are expected through Wednesday, but the return of deeper monsoonal moisture will allow temperatures to fall back to near seasonal levels by Friday. Any thunderstorms that do develop may produce gusty and erratic outflow winds. Otherwise, 20-ft winds will generally follow normal diurnal trends at less than 15 mph. Climate Another day of record to near record highs tomorrow across southeast arizona. Below are the forecast highs for Wednesday versus the daily record highs for selection locations across southeast arizona.

Prev discussion issued 220 pm mst Tue aug 20 2019 very hot for august with record to near record high temperatures around today and once again tomorrow. Excessive heat warning is in effect until 8 pm Wednesday for the lower elevations of pima, pinal and graham counties. Moisture limited across the area today with values mostly less than 1". The exception is right along the az nm border where values are slightly above 1". So a few storms possible along the az nm border and also along the intl border east of nogales. For tonight, will see low level moisture values increase associated with outflows coming out of new and old mexico. The outflow out of new mexico may generate a few showers storms across cochise county later tonight that may persist into Wednesday morning, per uofa wrfnam. Wednesday: pwat values increasing into the 1" to 1.30" range with highest values south of tucson. This will result in an increase in thunderstorms, in the isolated to scattered range mainly south and east of tucson. Thursday: pwats will be ranging from 1" east to over 1.5" west with best chances for storms being west and south of tucson. Localized heavy rainers with light and variable steering flow. Friday: the steering flow becomes more easterly across the area and combined with pwat values similar to Thursday and a weak inverted trof passing through sonora looking at the most active convective day in almost two weeks with the potential for activity to continue into the overnight hours. Saturday: upper level ridge axis north of the area will put the area under NE flow aloft which will bring an increasing chance for a rim shot event. Sunday: lingering moisture around for the chance of afternoon and evening storms. Monday and Tuesday: conditions start to dry out with lowering pwat values as upper high center settles over the area. Temperatures will be cooling later in the week and continuing into the weekend where highs could be at or a few degrees below normal. That will be short lived as highs warm back above normal early next week with the potential for near record highs once again next Tuesday.

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.
