Marky’s Tuesday Forecast: Cool Conditions at Coors Field

Here I sit on my back patio, laptop in lap. I pause and pick up the Canon PowerShot SX50 HS that sits beside me, as a ruby-throated hummingbird has caught my eye.

It hovers from flower to flower like a Harrier jet, which, coincidentally, is also named after a bird. I can go find a hoard of northern Harriers at Parker River National Wildlife Refuge at any time I so choose to … oh yeah, the weather.

Currently, it's about room temperature in Ipswich, Mass. and I squint my eyes to shield them from the overcast glare that the sun can't seem to overpower.

Once again, there'll be below-average hitting conditions in Boston, although that didn't stop the over from hitting last night.  But what you really want to be paying attention to is Coors Field.

Maybe I can give my sister a call and have a firsthand report.

Our Weather Rating distills the hitter-friendliness for a particular game into one number. It is a proprietary Fantasy Labs model and is shown on a scale of 0 to 100. The Weather Rating does not account for potential rainouts; rather, it simply examines all relevant atmospheric conditions (temperature, altitude, wind speed, humidity, and so on) to determine how batted-ball distance will be impacted.

Highest Weather Ratings

• Braves at Pirates: 71
• Cubs at Tigers: 69
• Phillies at Nationals: 65

Wait, what's this? I see three ratings here and none of them end with "at Rockies." What the …

Indeed, the game at Coors currently has a 62 rating. There was one instance in July when it had a 63, and once in June it had a 65.

Seven and 16 runs were scored in those games, respectively, so just keep in mind that Coors is still a good hitter's park regardless of weather due to its spaciousness.

Temperatures will be in the mid-60s, with winds blowing in and a chance of rain, which we will get to in a bit.

Where the Weather Rating is actually the highest, in Pittsburgh, we find an over/under of just 7.5. A large percentage of dollars is hitting on the under, which caused a sharp move from 8 to 7.5.

The interleague affair in Detroit has a much loftier total of 9, which is likely thanks to the winds blowing straight out with some pace.

Lowest Weather Ratings

• Rangers at Athletics: 36
• Indians at Red Sox: 39
• Astros at Mariners: 40

The total tonight in Boston opened at 9.5 — a run higher than yesterday's — because of the poor pitchers on the hill. I mean, the guys who started last night are making about 15 times more than the two tonight.

They're also poorer in the talent department. The Weather Rating is about 10 points higher than last night's thanks to a bump in humidity and a shift in wind direction from in to left to right, and the total has dropped from 9.5 to 9.

More than 60% of bettors are on the under in Seattle, which has remained at 8.5 since opening. The conditions actually are quite nice for Seattle, with temperatures around 80, but to be quite frank, the ratings seldom reach 50 at Safeco.

Rain

Yesterday was a rather simple day on the rain front, but today brings no such ease.

• Phillies at Washington: We've got ourselves a Flash Flood Warning right up until game time in Washington D.C., but after that, the rain should be scattered. This gives us a chance to play, but not a guarantee, as the rain may pick up again later in the night.
• Braves at Pirates: Pittsburgh will also be pretty rainy before the game, but the chances of precipitation drop by first pitch. If it lingers like the song by the late Dolores O'Riordan and the Cranberries, we could be in for trouble.
• Padres at Rockies: As far as rain likelihood during the actual three-hour game window, this one takes the cake. Depending upon the source, there's a more than 80% chance of rain at times, which will likely scare daily fantasy sports players away from playing hitters at Coors on this odd day.

Other games with slim chances of rain include Cubs-Tigers, Giants-Mets and Twins-White Sox.
