The big lumbering upper level low responsible for this week of ever present shower threats is just about out of here. A storm building out in the Plains will drop kick this slug into the ocean tomorrow. However, the first safely dry day is not until Saturday, but at least it is the weekend! After days on end of perfectly seasonable spring temperatures, good old summer is dying to make an appearance. Look for 80s to set up for an extended stay starting this weekend.
Today (Thursday): Humid air shows itself in the form of some patchy fog this morning. Do not be surprised to see the sun making occasional appearances in the morning. Showers and an occasional thundershower (80% chance) are most likely to strafe the area in the afternoon. There could be a few strong wind gusts with the storms but most of the day is nearly calm. Highs should easily reach the mid-to-upper 70s. Confidence: Medium-High
Tonight: A cautious person would keep the umbrella handy for the evening since there is still a 60% chance before midnight. Minimal breezes are a blessing given the showers. Readings gradually slide to the mid-to-upper 50s. Confidence: Medium-High
Keep reading for the forecast through the weekend...
Tomorrow (Friday): The difference today is that those afternoon showers (40% chance) drift down from the north rather than coming up from the south as they have been the past few days...a sure sign that the storm is finally pulling away. A light breeze out of the north is another hint that the storm’s departure is underway. The bulk of the day will have limited sunshine but it is still enough to help highs reach the mid-to-upper 70s. Confidence: Medium
Tomorrow night: Showers should finally be out of the picture with just a 20% chance in the early evening. By the time the sun sets clearing begins. A lovely night for a stroll with readings hanging in the upper 60s to lower 70s. Lows should slip to the mid-50s in the suburbs but hang in the lower 60s downtown. Confidence: Medium-High
Saturday is a gardener’s delight! I will be talking about such things later today in fact. Actually this is likely to be a 10 in most anyone’s book. The skies will be mostly clear with just a brief afternoon upturn in those puffy fair weather clouds. Winds are light and highs manage to crack the 80 degree mark in many areas. Highs in the upper 70s to lower 80s give us every reason to expect 70s to hang on through the evening. Lows should only fall to the upper 50s to lower 60s. Confidence: Medium-High
Sunday starts out promising with loads of sun and temperatures charging quickly through the 60s into the 70s during the morning. The problem is the storm in the Midwest that helped kick out our last storm has a band of showers associated with its warm front that is likely to cloud up the afternoon. Highs are unphased and make the lower 80s in nearly all areas. It is highly unlikely that showers occur with this warm front but if they do, 20% chance, it would be around sunset. Overnight lows only fall to the low-to-mid 60s. Confidence: Low-Medium
Monday is a tough call. More showers from the Midwest storm are going to be trying to scale the Appalachians and some are likely to “git er done” by afternoon (40% chance). The more abundant clouds could keep highs a little more contained topping out in the upper 70s to lower 80s. Confidence: Low-Medium
