With the observations, I did try setting a higher La Nina amplitude threshold (DJF Nino 3.4 SST anomaly amplitude greater than 1 deg. AccuWeather senior meteorologist Paul Pastelok and his team say that this winters setup is complicated by several other factors including the Hunga Tonga volcanic eruption in the early days of 2022.

Winter Weather Forecast for 2022 - 2023 | From Direct Weather But that does not mean it has no impact. The notably small sea surface temperature differences between the wet and dry groups indicate that the sea surface temperature pattern plays a very minor role in the Southwest precipitation differences during La Nia, according to the climate model. The Met Office's three-month outlook, for example, suggests this winter is half as likely as usual to be classified as wet. I'm pleased you're joining us today to discuss the Southwest Gas Holdings fourth quarter and year-end results. So, next, we want to know if there are any consistent differences in the sea surface temperature pattern between La Nias that lead to wet versus dry early winters in the Southwest.

Also, the southwest is expected to be dry during the winter months, which won't help the drought. To analyze the effect of different sea surface temperature patterns on early-winter precipitation in the Southwest during La Nia, I first defined two groups: the wettest 20% and driest 20% of simulations.
