The weather forecast for Dec. 9 is partly cloudy with a high of 40 degrees.

Perfect weather for the opening of an ice cream shop.

Weckerly's - the homegrown micro-creamery founded four years ago in the kitchen at the Green Line Cafe in West Philadelphia - is ready to start scooping at its first brick-and-mortar location: a tiny storefront at 9 W. Girard Ave., next to Green Aisle Grocery and just west of Frankford Avenue.

Doors will open 4 p.m. Dec. 9, and snacks and beverages  - including beer from St. Benjamin Brewing Company and cheese from the Creamery Collective - will be available.

Weckerly's is the passion project of Jen Satinsky, a pastry chef, and her husband, Andy, a bicycle mechanic whose work with the brand includes spokesman. (Bike humor never gets tiring.)

Their French-style custard ice cream, now made at Globe Dye Works in North Philadelphia from locally sourced milk, cream, eggs, and other ingredients, will be sold in scoops as well as ice cream sandwiches.

Flavors ($4.75 single, $7 double) include Whole Bean Vanilla; Hot Chocolate, a chipotle cinnamon spice chocolate with swirls of handmade toasted marshmallow fluff; Jim’s Secret Stash, a bronze fennel from Philadelphia’s Heritage Farm with a salted licorice swirl; Lemongrass Cherry, a variety of lemongrass and Pennsylvania-ground sour cherries; Apple Cider Sorbet; and Peanut Butter Populi, a crowd-sourced flavor made of peanut butter ice cream with chocolate and peanut butter honeycomb candy. (Peanut Butter Populi was selected from suggestions and input from fans via social media.)

Ice cream sandwich flavors will include Black and White ($5); Crème Fraîche Cranberry on spiced shortbread ($5); and Baglr’s Rhapsody ($6), a collaboration with Fishtown's Philly Style Bagels, featuring layers of cream cheese ice cream and bagel ice cream sandwiched between an IPA cookie with toasted sesame, fennel seed and sea salt.

Hours will be noon to 9 p.m. Sunday through Thursday, noon to 10 p.m. Friday and Saturday.
