May 16th, 2024: Chances for Elevated Convection Today

Image
  Synopsis A closed low over New Mexico will promote a chance for elevated showers and thunderstorms across the eastern half of AZ through this evening. A dry sub cloud layer will prevent any significant rainfall accumulations, and the primary impacts will be occasional lightning strikes, gusty winds, and blowing dust.   Current Conditions At 9:45AM MST, visible satellite imagery displayed a weak, small cluster of elevated showers and isolated thunderstorms in the Phoenix vicinity moving rapidly southeastward. Visible satellite imagery loop overlaid with GLM flashes this morning courtesy of College of Dupage. SPC 500mb analysis this morning showed a weak closed low over Central New Mexico, and a subtle shortwave on the backside of the low over AZ.  SPC 500mb analysis as of 17z this morning. The region of convection near Phoenix this morning is associated with PVA ahead of the subtle shortwave.  This mornings 12z TUS sounding measured a relatively dry and st...

August 28th: Chance for Showers and Storms in Southeastern AZ; Extreme Heat Continues Across Lower Deserts

Image
  Synopsis Rinse and repeat type pattern today with just enough low to mid level moisture and instability for a chance of afternoon and evening storms across southeastern AZ (including Tucson). Another day of extreme heat with temps around 105 degF in Tucson with temps between 110 degF and 115 degF between Phoenix and Yuma. Current Conditions  Visible imagery already showing a few weak cells developing over the sky islands and White Mountains. Visible Imagery as of 19:00z courtesy of the College of Dupage. SPC 500mb analysis displays the mid level anticyclone centered over Southern CA and weak northerly/northeasterly mid level flow across Arizona.  SPC 500mb analysis as of 19:00z. The 12z TUS sounding still measuring marginal thermodynamics and moisture below 500mb with some subsidence in the upper levels above 500mb.  12z TUS sounding courtesy of the SPC. Today's Forecast Synoptics The only real synoptic change is the more northeasterly mid level flow...

August 5th: Hot, Dry Conditions Today & Tomorrow, Return of Moisture and Thunderstorm Activity Next Week

Image
  Synopsis Arizona will remain abnormally dry and hot today and tomorrow due to the close proximity and strength of the mid level anticyclone. Excessive heat conditions will most likely continue through Monday, but a cool down is expected starting early next week. The combination of southerly flow aloft and a weak tropical cyclone in the eastern Pacific will lead to an increase in moisture and thunderstorm chances next week as well.  Current Conditions Current SPC 500mb and 300mb analysis this morning displays the 500mb high anchored over south-central New Mexico and an upper level jet streak over the west-central CONUS.  SPC 500mb Analysis at 17:00Z this morning. SPC 300mb Analysis at 17:00Z this morning. This upper level pattern promotes extreme synoptic scale subsidence due to the close proximity of the 500mb anticyclone as well as being in the right exit region of the jet streak (upper level convergence). This is reflected quite well in the 12z TUS sounding ...
