???? 據(jù)天然氣新聞2021年2月6日紐約報道，2月5日，美國各地2月6日至8日的天然氣現(xiàn)貨價格出現(xiàn)飆升，據(jù)預(yù)測，一個重大的寒冷天氣事件將導(dǎo)致美國天然氣供暖需求飆升，并導(dǎo)致天然氣產(chǎn)量凍結(jié)。
????美國大陸中部地區(qū)的氣價飆升至2019年以來的最高水平。
????2月5日，美國天然氣銷售商尼科爾管道公司（NGPL）的天然氣價格在交易中環(huán)比上漲了50美分，結(jié)算價為3.43美元/百萬英熱單位，這是自2019年3月以來的最高價格。同樣，由于芝加哥的氣溫降到了零下，NGPL-Midcontinent Pool天然氣的現(xiàn)金價格當(dāng)日上漲了47美分，報收于3.34美元/百萬英熱單位。
????美國國家氣象局宣布，襲擊落基山脈北部的冬季風(fēng)暴系統(tǒng)將于周六下午晚些時候抵達美國中西部地區(qū)，內(nèi)布拉斯加州和伊利諾伊州將迎來降雪。芝加哥2月7日的最低氣溫預(yù)計為零下5度，風(fēng)寒指數(shù)為零下10度。
????美國中部地區(qū)的天然氣總需求預(yù)計將在今年冬季達到最高值，2月7日已達到380.6億立方英尺/天，而美國上中西北部地區(qū)的天然氣供暖需求預(yù)計將攀升至278.4億立方英尺/天，在兩天的時間內(nèi)增長32%。隨著美國各地氣溫的下降，該地區(qū)滿足不斷上升的需求的供應(yīng)可能會放緩，這可能為美國大陸中部天然氣價格的上行帶來更多風(fēng)險。
????2月4日，芝加哥市-關(guān)口3月天然氣合約已經(jīng)上漲20美分，至2.97美元/百萬英熱單位，而夏季天然氣合約同期平均上漲10美分，至2.78美元/百萬英熱單位。

????Polar vortex spikes US spot gas prices across the country
????Cash prices for Feb. 6-8 flows of natural gas surged across the US on Feb. 5 as a major cold weather event is forecast to spike heating demand for gas and cause production freeze-offs.
????Midcontinent prices jump to highest levels since 2019
????Natural Gas Pipeline-Nicor was trading 50 cents higher on the day to settle to $3.43/MMBtu Feb. 5, its highest price since March 2019. Likewise, the cash price for NGPL-Midcontinent Pool jumped 47 cents on the day to settle to $3.34/MMBtu as temperatures in Chicago reach negative lows.
????The National Weather Service announced that the winter storm system hitting the Northern Rockies will reach the Midwest later Saturday afternoon, bringing snowfall from Nebraska to Illinois. Chicago temperatures Feb. 7 are forecast to reach a low of minus 5 degrees, with a wind chill of minus 10.
????Total Midcontinent demand is projected to reach its highest values this winter season at 38.06 Bcf/d Feb. 7, while heating demand in the Upper Midwest is expected to climb to 27.84 Bcf/d Sunday, a 32% increase over a two-day period. Supply into the region to meet this rising demand may falter as temperatures drop across the US, which could provide more upside risk for Midcontinent prices moving forward.
????The Chicago city-gates march contract has already spiked 20 cents on the day to $2.97/MMBtu Feb. 4, while the summer strip average climbed 10 cents over the same period to reach $2.78/MMBtu.
