FORECAST IN DETAIL


We have a cloudy, cool, somewhat damp journey ahead of us. So enjoy today’s relatively simple, dry forecast of breezes and increasing clouds. Relatively warm high temperatures today may even near 60 in some spots, but we will chill down into the 40s in the coming days. Risks to my forecast include greater coverage of rain and clouds, so our temperatures could be cooler, and ground damper. We’ll watch it for you though!

Today (Friday): Use a sick day if possible since this could be the best of the next few. Sunshine should dominate the morning hours, but periods of clouds look more likely during the afternoon. Hard to pinpoint temperatures that could vary depending on your local cloud cover. Despite this, temperatures should still get into the mid-to-upper 50s. South of town, sunnier spots do have an outside chance of hitting the 60 degree mark. Note that with slightly gusty southwest breezes (5-15 mph), especially during the afternoon, it might feel less-than-springlike. Confidence: Medium

Tonight: Final cloud reinforcements move in overnight and seal their stronghold on our region for the coming… few days? Rain chances exist after 10pm or so, making an umbrella a good bet if staying out late. By just before sunrise, most of us have about a 30% chance of having seen a shower to dampen the ground just a bit. Temperatures bottom out around 40 degrees for most of us, perhaps as high as mid-40s downtown. Confidence: Medium-High

Tomorrow (Saturday): It may be a damp a chilly (40s for temperatures) morning for runners of the Rock ‘n’ Roll marathon. Overcast skies have a decent (60% chance) of wetting the race course. Bands of showers are a good bet until mid-afternoon or so but at least the showers don’t amount to a complete soaking. East-northeast breezes become variable, but should stay tame, thank goodness. During the afternoon, high temperatures briefly climb up around 50 degrees to low 50s in dryer spots. We may get a small break in showers, but they should pepper the day with drops. Hopefully we can see a ray or two of sunshine? Confidence: Medium

Tomorrow night: Any break in clouds should close up again but, luckily, shower chances reduce to the 10-20% chance range. If you check radar before you head out and it looks clear, you may be able to skip taking the umbrella. You might want to grab, though, a scarf or light sweater (green ones, of course) with temperatures heading down into the mid-to-upper 30s. Confidence: Medium

S unday (St. Patrick’s Day): Did you see that ray of sunshine? It could have just been imaginary, like leprechaun gold. Skies stay mostly cloudy but showers *should* stay sparse (10-20% chance) as it appears now. Perhaps grab a small umbrella if heading out for a Guinness. My forecast confidence is a bit low because a front could stall out near us and pulse some rain our way. The afternoon has the highest chance of any rain. We’ll have to keep an eye on it. If it starts trending wetter (and cloudier) my forecast high temperatures in the mid-40s to around 50 could be too optimistic. Confidence: Low

A LOOK AHEAD

Sunday night may have showers, perhaps composed of both rain and a few flakes of snow (mainly north and northwest of town). Odds are better it could dampen us a bit more than earlier in the day. Perhaps still no more than just a few hundredths of an inch? Low temperatures stay chilly, but about average for March, in the mid-to-upper 30s. Confidence: Low-Medium

Monday stands about the same chance of being mostly cloudy as Sunday, yet higher (50%) chances of showers exist. High temperatures stay a bit raw, in the mid-to-upper 40s. More rain and clouds than I currently expect could reduce temperatures further, closer to lower 40s. Confidence: Low-Medium

Tuesday is when sunshine gets fed-up and attempts more frequent peeks through semi-overcast skies. There is the potential for some rain (30-40% chance) to continue threatening us, but I am optimistic it will not be an all-day event. High temperatures should manage to climb into the upper 40s to mid-50s (if sun reigns in the afternoon). Confidence: Low
