Phoenix weather: Cooling downPosted: Updated:
PHOENIX -- Water vapor imagery shows a high-amplitude flow pattern over the northeast Pacific and North America, with a narrow ridge over and near the west coast getting pinched from the west by an advancing Pacific low-pressure system. The result will be moderate temps into the weekend.
A weak weather disturbance, which brought high clouds last night and early this morning, is shifting eastward, leaving behind clear skies. We anticipate minor cooling the rest of the week. No precipitation is in the forecast through the weekend.
Friday and Saturday, a weak shortwave will slide through the Great Basin. Current model runs are now introducing an increase in moisture. For the most part, the focus for any precipitation chances reside over northern and eastern Arizona Friday afternoon.
Impacts this far south should be minimal, perhaps a brief increase in cloud cover and some local breezes across the south Friday and Saturday. But it doesn’t look like we’ll see any rain around the Valley.
Highs will continue to drop, and by Saturday and Sunday, we’ll be in the low 70s.
