September 27, 2020 - The National Weather Service Hanford Office reports the combination of very dry fuels, gusty winds and low relative humidity can contribute to increased fire behavior for the next couple of days.
We are not expecting Critical Fire Conditions, however we are forecasting conditions to become more favorable for increased fire behavior.
East winds 10-15 mph with gusts to 25 mph and RH values getting down to 20 to 30 percent.

Area Forecast Discussion National Weather Service Hanford CA 150 AM PDT Sun Sep 27 2020 .SYNOPSIS...Dry weather will continue over area for the next several days. High temperatures will rise to well average by Monday and remain above normal through the end of the week. && .DISCUSSION...IR imagery showing some high clouds pushing southward through our CWFA this morning. These clouds will continue to push slowly southward today and should push south of our area this evening giving way to clearing skies tonight. Meanwhile, an upper ridge is amplifying off the western CONUS coast near 135W. The ridge is progged to propagate eastward today and build inland tonight and Monday. The ridge will turn the upper flow offshore tonight and may produce some gusty easterly winds over the ridge tops in the Sierra Nevada and Kern County Mountains this afternoon through early Tuesday which might result in some smoke from the large fires in the Sierra Nevada being blown into the San Joaquin Valley on Monday. It will also result in elevated fire weather concerns this afternoon through early Tuesday along the Sierra Nevada crest and along ridge tops in the Kern County Mountains. The ridge building inland will also produce rises in heights and diurnal thicknesses and as a result temperatures will rise to well above normal levels on Monday with afternoon highs in the San Joaquin Valley expected to be in the mid to upper 90s. The ridge is progged to strengthen over our area on Tuesday which will likely result in additional warming for our area. The winds aloft will turn more southerly which end the elevated fire weather concerns for the mountains. Winds will generally become terrain driven from Tuesday afternoon through the remainder of the week. The medium range models are in fairly good agreement with maintaining the upper ridge over the western CONUS through the end of the work week with dry conditions and much above normal temepratures continuing through at least the end of the week. The one uncertainty that exists for temepratures forecast this week is how much impact will smoke from the large fires in the Sierra Nevada have on daytime temperatures. Progs are indicating the ridge will weaken some next weekend as an upper trough deepens off the western CONUS coast. Temepratures will lower some next weekend in response to lowering heights and thicknesses, but remain well above seasonal averages. Dry conditions will prevail across our area at least through next weekend with no signs of precipitation.Source: NWS
