NWS Forecaster Discussion
728 fxus65 kpsr 041729 afdpsr Area forecast discussion National Weather Service Phoenix Arizona 1030 am MST Friday Jul 4 2008 South-central and southwest Arizona...and southeast California forecast discussion Update...updated aviation discussion. && Synopsis... high pressure aloft will move towards The Four Corners region today and then begin to drift slowly southward into central Arizona late in the weekend. This means that the threat of afternoon and evening showers and thunderstorms will continue today and Saturday...mainly over south-central Arizona...before diminishing somewhat on Sunday and Monday. A return to hotter weather is likely by the middle of next week. && Discussion... trend of increasing moisture/decreasing temperatures continues. Latest kpsr 12z sounding came in with a precipitable water of 1.6 inches. Modified sounding supports scattered convection this afternoon with SBCAPE between about 900 j/kg and 1400 j/kg...depending on how much low-level moisture gets mixed out. Latest forecast updates include a lower maximum temperature for today and an increased chance for precipitation this afternoon and this evening...even across the southwest deserts. Previous discussion... significant push of low-level moisture has taken place overnight as southerly outflow winds from large mesoscale convective system over northwest Sonora have made their way into the County Warning Area. Both kiwa/kyux vwp indicate moderate S/southwesterly winds in place across the region in the lowest 5k feet...with 40kts indicated on the kyux radar between 2 and 3k. Surface dewpoints now in the upper 50s to middle 60s in scntrl Arizona...rising well into the 70s out in western County Warning Area...with 78 degree f dewpoint in Calexico at 09z. In light of the significant moisture push...along with the fact that min temperatures most places have dipped below criteria and will likely remain below criteria through Saturday...have decided to cancel the excessive heat warning that was in effect for scntrl Arizona today...and the watch that was in effect for Saturday. It will still be near or slightly above normal temp-wise...but quite a ways under local criteria. Meanwhile...model soundings continue to look very unstable as one would expect with the added moisture now in place. And...with favorable northeasterly steering flows today...decided to hike up probability of precipitation a bit from what was inherited...still slight chance in the deserts...but chance probability of precipitation now in the higher terrain of zone 24. With less favorable steering flows and perhaps some working over of the air mass tonight...went with a bit lower probability of precipitation on Saturday than those today. Although gusty microburst winds will still be possible with any storm...threat of locally heavy rainfall is now increasing as well. In fact...storms last night in the SW greater phx area produced upwards of an inch of rain. Upper level high now near The Four Corners will drift southward late in the weekend...then reform off to our northwest. This should help to allow moisture to become more diffuse with time...and air mass should begin to warm back up next week. Have therefore kept probability of precipitation confined to higher terrain areas of zone 24 next week...and warmed maximum temperatures back over 110 degree hottest deserts. May eventually Need More excessive heat products by middle of next week...stay tuned. && Aviation... skies have cleared this morning across the area...but expecting another active day in the higher terrain surrounding the Phoenix area. Expect convection to develop by early afternoon to the northeast and southeast of kphx. Later in the evening...there is a chance of showers and thunderstorms across the greater Phoenix area. Did not include mention of thunderstorms as uncertainty is still high...but will amend later if trends indicate otherwise. Confidence is high enough that outflow from mountain thunderstorms will move across the Phoenix area later tonight...with gusty winds mentioned. In western Arizona and southeast California...south-southeast winds near 15 kts extend up to 5 thousand feet. A few gusts to 25 kts will be possible...especially along the lower Colorado River valley. Thunderstorms are not expected to affect kyum/kblh/kipl during the period. Aviation discussion not updated for amended tafs. && Fire weather... by Monday...look for a Pacific low pressure system to move across the western states...bringing slightly drier but hotter air to our area. However...enough moisture will remain for a slight chance of showers and thunderstorms in the higher elevations east of Phoenix. By Tuesday...the Phoenix area could see afternoon highs up near 114...and in the Yuma area look for highs near 117 degrees. Along the lower Colorado River valley and Joshua Tree nm...minimum relative humidity values on Monday and Tuesday could dip to less than 15 percent. && Psr watches/warnings/advisories... Arizona...none. California...none. && $$ National Weather Service Phoenix is on the internet at weather.Gov/Phoenix Discussion...Hirsch/estle aviation...Rogers fire weather...Sipple
