(EXTRACTED FROM FXUS65 KPSR 261207) Updated at 1200z South-Central Arizona including KPHX, KIWA, KSDL, and KDVT: A slow moving low pressure system southwest of the area is bringing plenty of uncertainty in the forecast but trends and guidance continues to suggest showers and embedded storms likely to move through the terminal area this morning, primarily between 12/14Z through 16/18z, depending on the terminal. Showers and storms may produce downbursts, heavy rain that reduces visibility, blowing dust, and extended periods of variable wind directions and gusts upwards of 25-30 kt. Cigs will likely drop between 070-110 with periods of lower cigs near 050 possible. During a lull in showers during the late morning through parts of the afternoon, confidence in wind direction are uncertain and may depend on how the morning activity clears. Periods of NW-NNW-N-NNE seem likely during the early afternoon and may become strong in excesses of 10-12 kts with gusts in the upper teens if convection over the higher terrain creates an outflow. Additional showers are possible again this evening along with breezy to gusty SE outflow windshifts from stronger thunderstorms east of the Valley. Gusts near 17-28 will be possible. Southeast California/Southwest Arizona including KIPL and KBLH: Showers and thunderstorms may brush the terminal area Sunday but are mostly expected to stay east of the Colorado River. Easterly outflows are possible, particularly at KBLH, but confidence is too low to mention in the TAFs at this time. Otherwise, winds will shift from SSE to W through the day at KIPL while speeds remain AOB 9 kts. At KBLH, non-thunderstorm related winds will also have speeds AOB 9 kts with directions generally favoring some southerly directional components. SCT-BKN mid and high decks expected at KBLH and FEW-SCT mid-high cloud decks at KIPL.
