Brief Summary

PPD Threat: CHC (low), KC (low), COL

Delay Threat: ATL (low)

• SF at ATL will see a few scattered thunderstorms near first pitch. PPD RISK VERY LOW, LOW TO MODERATE DELAY RISK.

• The SPC (Storm Prediction Center) has both Kansas City and Chicago in the risk area for thunderstorms tonight. Let’s start in Chicago for LAD at CHC. The current radar ;ooks somewhat bad, but my first inkling is that this may be overblown. A stationary front is to their north while a cold front is to their west. Basically, there is no direct “forcing” right on top of them, they are just in a warm and humid airmass with thunderstorms forming out ahead of the cold front. This generally means that the rain is NOT steady and thunderstorms will weaken after the sun sets until the cold front is closer to them. Thus, while this area needs to be watched carefully, I think they will be able to play. LOW TO MODERATE CHANCE OF PPD; MODERATE TO HIGH CHANCE OF DELAYS.

• TB at KC is a higher threat for a PPD than the game in Chicago. Simply put, the cold front is right on top of them this evening. That means thunderstorms will be numerous. The short term model I trust the most really does not agree with my statement that this game is more worrisome. However, there are other models that do. But even these show that the back edge is near KC and that they should be able to play. LOW TO MAYBE MODERATE CHANCE OF A PPD; MODERATE CHANCE OF ANY TYPE OF DELAY(S).

• CIN at COL will also see some rain. This looks rather worrisome. The reason for this is that on a “normal” day we have a reversed look to the radar, the rain is in the mountains and the Plains east of the mountains are dry. The current situation is complete reverse the normal. And the reason is rather simple. Instead of a west wind that is a downsloping (thus drying) flow for Denver, we have an east wind which is an uplsloping wind (which is wet). Rain could reform over and over again, and the National Weather Service certainly has the area wet on its maps. MODERATE CHANCE OF PPD OR ANY TYPE OF DELAY(S).

Good Hitting Environments

• Summer warmth and humidity will cause the air density to be low for SF at ATL.

• CIN at COL will have the huge advantage of very low air density thanks to being more than 5,000 feet above sea level.

Poor Hitting Environments

• As compared to many of the outdoor games that are played with early summer warmth and humidity, the two California games (LAA, OAK) and games played indoors (probably ARI, MIL, MIA) will be at a disadvantage, though MIL seems to favor hitters whether or not the roof is closed.
