Area Forecast Discussion National Weather Service Hanford CA 1217 AM PDT Tue May 17 2022 .SYNOPSIS... Dry weather continues across the region today as high pressure starts to rebuild. A warming trend will occur Wednesday and Thursday, taking the area 10 degrees above normal. Cooler Friday with temps rebounding sharply over the weekend. Afternoon highs in the upper 90s will be possible early next week. No rain is forecast for at least the next 7 days. && .DISCUSSION... Onshore gradients are finally weakening over the area early this morning, which will allow for winds to relax over the Kern County Mountains today. Afternoon highs may trend a degree or two above yesterday as high pressure starts to build over the Eastern Pacific. The cooler airmass we had Monday/Tuesday will quickly modify on Wednesday and Thursday as high pressure over the Eastern Pacific builds. Afternoon highs in the mid 90s are expected across the San Joaquin Valley both days. Cooler and windier conditions will occur late Thursday into Friday as a trough of low pressure enters the Great Basin. Ensemble guidance is showing this trough exiting the area rather quickly, though. So that means that the cooling trend we get on Friday will be short lived. High pressure looks to reestablish itself over the Eastern Pacific this weekend, which will allow for afternoon highs to increase several degrees on Saturday compared to Friday`s highs. Low 90s for high temperatures is being advertised by the latest NBM run on Saturday, with mid 90s forecast for Sunday. Ensembles generally show the ridge strengthening Monday, which would allow for highs to run up a few more degrees. This means upper 90s for afternoon highs look conceivable for Monday, and then possibly again on Tuesday. NBM probabilistic guidance has backed off a bit from yesterday with regards 100 degree heat on Monday. It is now showing 25-35% chance of 100 degrees for Monday. Regardless of if hits 100 or not, it will still be quite hot for this time of the year. Again, we are urging people not to enter area rivers to seek relief from this heat through, as currents can be swift and waters can be much colder than expected, leading to dangerous conditions. Dry weather is expected to continue for at least the next 7 days. && .AVIATION... VFR conditions will prevail throughout Central California for at least the next 24 hrs. && .AIR QUALITY ISSUES... None.Source: NWS
