Sunshine Sunday Turns Stormy as Major Spring Snowfall Looms for Monday
Forecast for Sunday, April 13, 2025
The Geraldton and Greenstone region is enjoying a tranquil and sunny start to what promises to be a very eventful weather week. As of 7:00 AM EDT, conditions at the Geraldton Airport are clear with a chilly temperature of -3.2°C. Humidity is high at 93%, and while the air is calm for now, change is quite literally in the air. Visibility is sitting at 16 km and barometric pressure is holding at 101.1 kPa—for the moment.
Today brings a beautiful, if brief, slice of spring. Expect mainly sunny skies this morning, with increasing cloudiness rolling in by early afternoon. Fog patches will lift as the sun rises, and we’re headed for a surprisingly warm high of 14°C. A light breeze up to 15 km/h and a UV index of 4 make this the best day of the week to soak up some sunshine. It’s your perfect pre-storm picnic window.
Tonight: Storm Brewing with Risk of Freezing Rain
Clouds will thicken tonight as a Colorado low begins to work its way into the region. Expect a 60% chance of rain showers this evening and overnight, with the added possibility of freezing rain creeping in during the overnight hours. Fog patches will re-develop after sunset, and winds will shift to the northeast at 20 km/h by morning. Overnight lows are expected to settle right at the freezing mark—0°C—setting the stage for a messy transition on Monday morning.
Monday, April 14: Winter Strikes Back with Heavy Snow, Freezing Rain & Gusts
The real drama begins Monday morning as the Colorado low rolls through. Precipitation will begin as rain or mixed precipitation, with a risk of freezing rain early on. By late morning or early afternoon, that mix will switch to heavy snow, with 10 to 15 cm expected through the day. Some local forecasts even suggest up to 25 cm by Monday night.
Winds will pick up noticeably from the north at 30 km/h, gusting to 50, contributing to local blowing snow and sharply reduced visibility. The temperature will hold steady near zero, and the UV index will dip to a low 1—not that many people will be out sunbathing during this snow-blasted Monday.
By Monday night, the snow (or possibly rain/snow mix) continues, along with local blowing snow and gusty conditions. The low will drop to -6°C, making for a wintry, slippery evening commute and snow-covered everything by morning.
Tuesday and Wednesday: Snow Sticks Around Before a Midweek Bright Spot
Tuesday, April 15, continues with periods of snow, more blowing snow, and continued windiness. The high will only rise to +2°C. Tuesday night brings cloudy skies and a 60% chance of more snow, along with a drop to -10°C—bundle up, folks.
Wednesday, April 16, offers a touch of optimism with a mix of sun and cloud and a 30% chance of flurries. The high will remain cool at +2°C, and the overnight low will dip even further to -11°C under clearing skies.
