FORECAST IN DETAIL

Today starts somewhat sunny, and stays mild albeit breezy. By tonight, most of us should get a small dose of rain with more coming into tomorrow. We may see some more sun before too long though, as the cold front passes through midday tomorrow. This new, cooler airmass gets us much closer to our average highs in the low 50s, and upper 40s to low 50s through Tuesday appear possible. A little more shiver before spring sets in for good?

Snow Potential Index: 1 (→) - Support for Sunday flakes miniscule. If any more than a few fall it would be kind of surprising.

Today (Friday): Let’s enjoy the morning, partly sunny, hours of the day today before clouds increase during the midday and afternoon. Shower chances in the afternoon only increase as time goes on, with a 40% chance probably becoming 50% chance by sunset. Showers should enter the region from the southwest around midafternoon and progress northeast from there. Winds at 10-15 mph from the south & southeast keep us fairly mild, with temperatures in the upper 50s to around 60. Extra sun might push us into the low 60s. Confidence: Medium

Tonight: Clouds fully take hold, with overcast skies likely overnight. There is about a 50% chance of lingering dinnertime/evening showers, then perhaps a small lull, with more (60% probability) showers & thunder after midnight or so. Lows should be relatively uniform -- in the upper 40s throughout the region -- with the mildest (50 degree?) readings downtown. Note a slight breeze out of the south, too. Definitely grab your umbrella if going out! Confidence: Medium

Tomorrow (Saturday): It looks pretty darn cloudy, especially during morning hours, during which showers and a thunderstorm may dampen us (70-80% chance). It is possible that there could be a somewhat solid shield of rain ahead of the approaching cold front. Grab the rain jacket if heading out early. You should notice changes once the front has passed through: clouds breaking, slight increase in wind and directional change to blow from the west/northwest. The afternoon sun could shine through enough to warm us a bit more, into the mid-60s toward 70 degrees (south of town especially). A few more showers could pop-up before sunset as well, so don’t put away that umbrella completely. Confidence: Medium

Tomorrow night: Some clouds try to put a veil over us, periodically; but, 5-10 mph winds out of the west continue to bring in chillier air which should cool us down into the upper 30s to around 40. Confidence: Medium

Sunday: Skies could be splendidly sunny with average highs in the low 50s. Our bodies will notice the cooler difference in temperatures! Some clouds could try to dot the sky in the afternoon -- perhaps even a small period of overcast skies are possible. It could hold highs in the upper 40s, but it isn’t too likely to be that cool. Confidence: Low-Medium

A LOOK AHEAD

Sunday night: Just a slight 10-20% chance of a few light rain showers mixing in with snowflakes -- mainly west and northwest of town, I’d say. Really we are not even looking at many clouds around to support precipitation, but it isn’t prudent to completely rule this out. Lows take a while to head toward freezing, toward dawn, ranging in the low-to-mid 30s. Confidence: Low-Medium

Monday could have a mix of sun and clouds, with a slight breeze. Temperatures will fluctuate with the number of clouds we end up seeing -- ranging from the mid-40s if overcast at times, to perhaps lower 50s with a greater amount of sunshine prevailing. Confidence: Low-Medium

Tuesday could start chilly but eventually sunny skies prevail and catapult temperatures toward the 50 degree mark. A bit below our average high temperature? It is possible! Stranger things have happened… Confidence: Low
