Today will be much cooler than yesterday with highs only reaching near 70 in the Valley. Chico will also be a little cloudier than Redding today. Winds are calm with conditions still expected to be dry today.
Friday, some in the Valley may not even reach 70 degrees, Chico included, with partly cloudy skies. The trough oflow pressure keeping us cool and cloudy leaves Friday night. This makews us sunny with a big warm up through the weekend. Some in the North Valley could break high temperature records once again. By Sunday Redding could reach the mid-80s with Chico staying in the upper-70s. The ridge of high pressure is anomolously strong for this time of year which is why the temperatures get so high.
By Monday the ridge of high pressure begins to weaken and move to the East. This allows for a few clouds to peak in during the evening hours and high temperatures to be a few degrees cooler than Sunday's.
Tuesday a strong weather system withy a cold front attached approaches the North State. Currently the models are split on what direction the low-pressure system will track. The track of the low will largely determine what impact the low has on us. Some take it into the Great Basin. This means we would have gusty north winds and dry conditions equalling high fire danger while the Great Basin gets wet. The other computer models have the system taking a more southerly track towards us. This would mean a chance for showers and snow showers in the mountains and the chance for scattered showers in the valley. The outcome should become more clear in a few days.
